| I inherited a Cooper Hewitt rectifier, 10 amp 125 volt by Westinghouse. The style # is 222324 and has mercury inside. Can you tell me about it and its' value? My Dad was a ham for 80 years and had quite a vast collection of parts, radios, etc.
Thank you very much! Faye Pulley Oh... his call was W4COC and he built several Tesla coils! He loved to show them to unsuspecting friends! |

| Wow, man! I think all my hair is standing up! The only thing more awesome than hearing you talk about these exploits and seeing the aftereffects would be to see them in slow motion! If you didn't want to spring for a high-speed camera, you could always do it Matrix-style! Set up a ring up disposable cameras, and use an electrical triggering system to take pictures, one after the other, very quickly. Or you could spin a wheel with an unexposed 35mm negative affixed to it very fast inside a light-proof drum. For a tiny length of time, just while the serious stuff was happening, you could open a pinhole aperture at the entertaining side (if you wanted frames, you could use a spoked wheel spinning past the aperture). HAHAHAHA! Just kidding, man! I thought it was in the spirit of this website to make crazy Goldbergian contraptions! Hope you can afford that high-speed soon! You could always just soup up and turbocharge an existing film camera (there I go again!) Love the site, Mike! Keep it up! These are things I will never, ever do, but I love it that someone else is! | |

| looking at your comments on the can crushing and possible super sonic speeds, Did you manage to create a viewable pressure wave from the sonic boom yet?
If you filled the room with smoke from a smoke machine you see at party's or nightclubs it should hopefully allow you to capture a stunning image it will also help with showing the intensity of the arc's "light show". |

| Hi,
Looking at the Display tube interested to see Projection Type. The AN-FPQ 6 radar console used these to display range, range rate, azimuth, elevation. The lamps used were GE 327, and there were at least 11 lamps-0=9 plus a decimal point, I have a vague idea there may ahve been two moore, + and -. In the Q6 application there was no way of turning the lamps off before withdrawing the module. The result was that when one lamp failed, as you withdrew the module most of the remaining filaments ruptured. It meant that you simply replaced the lot. The Q6 console had over 1000 GE 327 lamps in it. At one stage management att eh Carnarvon, Australia station, in an ecoonomy move, decreed that the radar could only hold 10 ready use spare lamps. Astounding stupidity. |

| PCB etchant: More than a few years ago when I was at school in the late '60s to 1972, I had great success with etching PCBs by adding hydrochloric acid to my starter solution of ferric chloride. I used a fish tank air pump to bubble air through. No heating. I assume the eventual etching solution was basically cupric chloride as copper also has the possibility of -ous and -ic as does iron. The oxygen from the air would take away the hydrogen from the acid. It was a rather nicer colour than ferric or ferrous chloride I remember. A nice clear green(I think). At the time nothing was really thought about for disposal of waste products. What does one do now responsibly? You may suggest this, but I haven't looked that closely. Richard | |

| Venner TSA 3336 digital frequency meter.
I commenced work at Venner in 1961 as a technician, one task was to get TSA3336s working. Instrument built of modules each module was a decade counter, binary counter etc. Decade modules BCD summed collector currents to drive moving coil digivisor; numbers sat in mid position during gate period. Solenoid locked digivisor coil to store the result during next count. Direct count , prescaler, reciprocal count were all there as per a modern frequency meter. Products under development at that time were Digital Volt meter, 100MHZ conter LF signal generator Pulse hight counter for nuclear and timers for Blue Streak.

| HiMike,
Love the site, Found it after starting construction on a nikie clock of my own using russian made 1N14 nixie tubes and 44 high voltage transistors to switch each element on from 6 4017 decade counters. The kit I am building was not my design, but was designed by David Whitby from Australia, email me if anyone would like the design or contact details for David Whitby. The kit uses a low voltage supply rail ( 12volt ac/dc ) with a step up switch mode power supply for the nixies. As I have small children, I thought that this would be safer.More so as I intend to enclose the whole thing in a clear perspex case.. Anyway, Love the site mike, Keep it up.. and don't let your hard work go down the tubes..... Dave Sargent, Australia.. |

| Hi, Great site, I just saw the receipe for making developer. (n the making PCB page). I think there is a decimal point missing in the Sodium Hydroxide measurement 400g in 1L is 10 molar, this much will not dissolve in 1L. It has to be 40.0g for a 1Molar concentration. This gives a 0.1 to 0.4 molar concentration when dissolved and about the correct conc. to bond with the Waterglass solution.
Keep up the good work. Steve |

| Fantastic site. I blame you for my feeling like crap at work yesterday... was about ready to go to bed, but looking for something on the web to alleviate boredom for a few minutes, then stayed up way late, transfixed by the vintage electronics, Tesla coils, etc. I've been tinkering with tube equipment since I was 12 years old, and currently work in IT, doing some telecom on the side. My first experience with a Tesla coil was when I was in school for electronics, and worked in the 'student resource center', where everyone came to check out the equipment and components they'd need. I noticed a small transistorized coil in a box, and hooked it up. I discovered it was great fun to keep it energized under the counter, with one hand on the electrode, and when an unsuspecting student came up to check something out, I'd hand them the pen to sign for it and watch them jump in surprise when a harmless spark would jump several inches to their hand. (good thing no one had a pacemaker I guess) Someday, perhaps I'll build one of these monsters after I buy a house, and if life graces me with the free time and inclination.
Thanks again for a great site. |

| High speed cameras have come down in price. A small camera plugged into your laptop can do as much if not more than Mikes new toy (the Kodak EktaPro TR1000). You can get 1000fps at 800x600 less than a tenth of the price of the Kodak when new.
Sorry if this sounds salesy, just thought you and your visitors might like to know, David (Lake Image Systems, and ex-Kodak) |

Something went wrong with his homemade "plasma cutter" made from a microwave transformer. Just a note to emphasize that this stuff can be very dangerous. Make sure that when you are expermenting that you know what you are doing and take every safety precaution and then some. | |

I am also working on a high power switched supply for between 800 to 8000J at 15kV DC using a "home brew" triggered spark gap. If you are interested, I'll send you info as I work on that project.
One comment, in your photodetector section you state that photomultipliers have been replaced with semicinductor devices. In many cases that is true, however, there are many scientific applications that still require the ultra-high sensativity and low noise that a good, shielded photomultiplier tube provides. This is especially true when trying to detect a single photon from a nuclear event |

| Begging your pardon, but I thought that my earlier email re type numbers/unknowns might be seen by more readers if I copied it to this page.
Hi, re your "unknowns" E1824, E2760, E1841, E3375, VX numbers and Barreter 306. I worked at GEC/MO-Valve between 1955 and 1961, on a technical apprenticeship, covering all types of valves. The E series were experimental (or pre-production) type numbers for new valves, which morphed into A series numbers when they were viable, such as the E1834 becoming the A1834, a regulator double-triode like the 6080. The E1824 is a disc-seal transmitting tetrode, probably in the UHF range. The heater/cathode/grid1 connections look about the same size as the DET24 triode's, which was good for 1000Mhz. (Much smaller co-ax structures were neccessary for any higher frequency). Perhaps a driver/tripler for linear 4CX150/250'S? The E2760 looks remarkably like a DET24. The "late" numbering (for example the A2293 triode was in production in 1956 for computers(!)--perhaps for Leo, at Joe Lyons, just around the corner at Brook Green) makes me think it was a development, perhaps for ruggedness. The E1841 beats me, I only saw B7G,B9A, Octal, B4 and numerous wire ended types on the vacuum pumps, but not the Loctal or B9G. I guess that it's a frequency-changer type of EF50/WW2 vintage. That means it would be an X-- in MO-V terminology. The CV10813 looks like the single triode version of a D77/CV140. There were other CV versions, I don't think there ever was a civilian version. The E3375 is a pentode/beam-tetrode line-output type valve, on the lines of the PL360, but might be the 6.3 heater version, like the EL360. The 119 magnetron is obviously Russian--bet you knew that! The VX Series numbers were late 1950's government contract numbers for development work. I think VX3--- was for GEC/MOV and VX9--- was for Mullard The barreter 306 was for 1955 GEC's tvs using series-ed 0.3amp heaters. It provided the potential drop to absorb the difference between the total series heater voltage and the mains. Because of its temperature/resistance co-efficient it "slugged" the switch-on surge and increased the life of the valve heaters. Unfortunately, by so doing, it itself died from surge burn-out. The guarantee was 90 days. They invariably died on the 92nd.! Their useful side effect was when the mains voltage dropped well below 240v-common in the 50's-the valves still had the correct heater power, and our TV would be the only one working in the street! Albeit with a reduced picture size. AEI CV165 crystal diode : microwave detector diode is all I know! Incidentally, my colleague Mike Forsyth and I "invented" the TT21 series transmitting valves which are based on the KT88 audio beam tetrode. We were ardent amateur radio geeks in those days, and the 807 was an icon, but low-ish in power. 150w was the governments limit. The 813 was far too big. The GEC equivalent 807 was the KT8C, a puny 1930's job. We realised the KT88's internal capacitances were quite low, and we persuaded the girls on the production line for the U19 rectifier (a top-cap anode job with a similar glass envelope) to put through 6 KT88s with a top-cap anode wire. It only "cost" us two nights each at Hammersmith Odeon, and as desirable 18yr. olds, was rather well worth it!). We approached the company station G3--- guys with these 6 for advice, and before we knew it, it was up, up and away. Thanks, Pat Cundy, and George Jessop. Regards, Bryan Lockey. PS The KB/ numbering triggers vague memories. Z was GEC/MOV, any following letter denoted the factory--but there were only Brook Green and Wembley by 1958. D was for Mullard at Mitcham, and a similar regime followed. Certainly Blackburn was still operating in 1958, but other details have escaped me. |
|
| bryan [ bryan.lockey@tesco.net ] Thursday, 2nd November 2006 - 11:51:29 AM | |
| Yo---oh! Tesla coils etc. We used these devices in the GEC/MOV valve/tube factories (1955) to check vacuum in the valves we made. They were in home-made boxes, ie not bought in products, with a protruding flat metal strip about 3inches long . To its pointed end, one offered up the dodgy valve, and, lo, and behold, it lit up different colours depending on the faulty processing causing various gases to foul the vacuum. Then we had to track down the contaminant in the components, or (usually) the duff vacuum pump. (We could get vacuum down to 10to the -5 mmHg with a good set of Edwards oil pumps,(pulsometers, then evaps) and better than 10to the-7mmHg with a mercury vapour set. I'm still alive at 67, despite 6 years in a mercury-heavy atmosphere!
I do remember those glowing vapours on the Tesla! (I had a s**t vacuum/glass mechanic for a while. But he was bloody good with the high speed grid winding machines.) We churned out CV138-CV4014-Z77/EF91-6AM6s at 1 every 7 seconds, at 2% loss. 24 hours a day. All year. At 3% loss you were deep in the s***t, as that was the break even point |

| bryan [ bryan.lockey@tesco.net ] Thursday, 2nd November 2006 - 08:33:59 AM | |
| I'm sure your "small thyratron" GXU50 is a mere Xenon gas version of the old GU50 mercury vapour rectifier. MOV/GEC type numbers used U for rectifiers, G for gas, and X for xenon.
But, a fantastic site, I'm back in the 50's! That's when I worked at MOV for 5 years. Thanks, Bryan |

| Looking at the various valves/tubes you have in your 'Electric Stuff', my memories go way back. Many of the items you show I have had and used.
The first radio I ever built was "The Yuletide Two" (with parts filched from my father's 'Radio Room'(He had a Constructor's Licence in the very early days when one read the newspaper by the light from 'Bright Emitters'). This led to building a series of radios and damaging my bedroom furniture with acid spilt from accumulators. All this when I should have been doing my homework. I remember the PM2DX was my favourite valve in those days. Some time later, I recall 'drooling' over the Mazda Ediswan catalogue wondering if I would ever be able to save up the 81 shillings the ZA1 Acorn triode cost.(Never did,I removed pin bases from triodes to get short leads to make VHF oscillators). Now over 20 years into retired from a life in Electronics-- From Army Service( No.1 Set onwards ), Electronics Research, Equipment & Systems Development to Marketing and Management. Involving Radio,Radar and EW (D.C. to 35 GHz). Still have my Amateur licence and gear but the computer has taken over much of my time by stealth!. Thanks, Mike, for stimulating the memories. |

| Re your sharplan laser. I'm an Ear nose and throat surgeon in Melbourne. We use Sharplan CO2 lasers for laryngeal surgery, attached to a binocular operating microscope. If you take the objective lens off the microscope it can work as a telescope. One day in the operating theatre we had a fly on the ceiling we couldn't catch. Surgeons don't like flies. Yours truly aimed the laser "telescope" from about 15 feet. One 0.1 sec zap after sighting with the red-dot (He-Ne) aiming beam and down it came, smoking and buzzing all the way. Shot clean through the thorax. Regular surgery isn't half so much fun! | |

| Awesome site, I haven't had a chance to look at it all, but I noticed with the Destruct-o-tron you're using 100? resistors to limit the current draw when charging. Have you considered replacing them with inductors? That would limit the current just as well and they shouldn't heat up. While I know efficiency isn't much of a consideration in these projects (if it were we wouldn't build them) those resistors are wasting a ton of power. | |
| Ed Watts (Ironic surname) [ Ed_Watts@verizon.net ] Wednesday, 28th June 2006 - 01:07:44 PM | |
| Some sort of high-speed recording of light output (versus time, obviously) of the "Exploding Guitar String" experiment would be quite interesting. The video appears to show a very quickly rising, extremely bright peak followed by a reduction in brilliance to a fairly low level. This then seems to give way to another lower peak with a slower rise time and a [relatively] long decrease to ambient. It is difficult to tell exactly what is happening early on due to the limited dynamic range of the camera, but it should be a relatively simple exercise to set up some sort of logarithmic photometric device and capture the output digitally or with a fast chart recorder.
This, as you probably know, is the signature of the flash from a nuclear blast -- depending upon the exact characteristics of the event with regard to brightness over time. If the flash could be properly produced to duplicate a nuclear event, it would be handy for calibrating bhangmeters and such. 73 Ed Watts KI6DCB |

| Absolutely my favourite site of the moment. I feel nostalgic warmth for the 'nixie' tubes, a vague fear and respect for the likes of the tramline rectifiers, and the tesla coil stuff had me chortling aloud to the screen! Marvellous work.

| Fascinating site! Great research, great graphics! Harkens back to the mid 60's when I was learning electronics. | |

| Dear Mike,
Fantastic site! Like many contributors I've spent hours looking at it and still haven't seen everything! Love the Nixies! For anyone interested in the neon flower lamps; lamps of this type are sold by Habitat, at Ј5 each. I think they do two types (at least I have bought 2 types) with standard ES fittings. Best wishes. Robert. |

| I don't know whether to curse you or congratulate you.
I have just spent HOURS wandering around the site. Still haven't finished the decorating, and the wife's arriving home soon. Absolutely fascinating. Carry on please. Rob S |

| Hi Mike,
Thanks for an excellent site. Very well done, so good to see an incredible and truly necessary trip through electronic history. Just feel sorry for anybody who wasn't pre 1965?...Silicon Revolution..hmm! Thanks for the care on the site. Graeme |

| I've been interested in nixies (didn't know they wre called that)since I saw some as a display in a bomb in a movie. I can't remember What the movie was but it was set in the 20's or 30's and about some superhero. Needless to say I found the sections relating to display valves very cool. Some of the clocks are incredible. | |
