Apparently, current hogging wasn't an issue, as it is/was with PN junction-based devices. Raymond

It isn't that you need to make the knob expand, it is simply a matter of warming the plastic a little so it isn't quite so brittle. You must, I repeat must, pull the knob straight off of the shaft.

Oh, give me a brake! ;-) BTW, I found it at the local 'Ollie's' store and I had a coupon for 10% off the entire purchase. Michael A. Terrell

Hi Raymond, You are correct. The TD design manuals (written in the 1960s when TDs seemed to have so much promise) do mention very high current Tunnel Diodes. For example, RCA Tunnel Diodes,

Apparently, it helps them stop in time. Harvey

You use what you have available. Leon Robinson ?? K5JLR Political Correctness is a Political Disease. Politicians and Diapers should be changed often and for the same reasons.

TD's as such, like the ones in 'scopes wouldn't be very susceptible to static discharge (look at their bipolar I-V curve) if it weren't for their extremely small junction size, resulting in a large

lightly gelled paint stripper is even better, if you don't miss! I was trapped in an old garage once, so I poured some into the cap for a can of spray paint and doused some very large and angry bees

Hello: To Lop Pol: The TDs can be destroyed by static or 60 Hz stray (eg from soldering iron) or by excess Tjuct, as they are germanium. I have soldered and curve traced with no problem on the TEK

I use the spray cans to clean under ICs and some other SMD components. I've never seen water based flux remover in a spray can, but I left manufacturing in late 2001 due to health problems. Michael

I can imagine the mess if you get it wrong!!! Given the knobs have a pair of "pegs" that engage with PCB mounted pots (assumed from photos I have found of the knobs and assemblies), heating the

I highly recommend one of Leo Bodnar's 40 pS rise time pulsers. No connection except very happy

Anyone have the 260-2500-00. Switch for the CG5011 module? Please send me email if you do. Electronixtoolbox@... Craig

Hi: On the subject of CRT rejuvenation... The filament, of a vacuum tube... like a CRT... the filament is tungsten, operated at a high temperature (This is necessary for adequate thermionic emission).

Thats good to know. I was under the impression that you could set parameters and needed a Windows PC to do that, so I bought a PG506 and a TD pulser.

NEVER, NEVER, NEVER USE AN ERASER TO CLEAN GOLD CONTACTS PERIOD! Anecdotal stories about personal "success" cleaning gold contacts with an eraser are based on ignorance to the damage being done.

Hi Dennis, I can confirm that Leo's pulser works fine from a typical USB power brick. It draws about 100mA at just over 5.0 volts. I have done this many times when I did not have a computer USB port

Avalanche pulse generators are not suitable for checking and adjusting transient response, unless you use some device (e.g. a piece of coax cable) to extend the length of the pulse. A transient is

Hi Lop Pol, The Leo Bodnar Pulser works perfectly well without a Windows computer. The computer comes in handy to change a few of its parameters, but the pulser works excellently with any USB power

Leo's pulser doesn't really need a windows computer. It can use one to set the pulse parameters, but you can do that with attenuators. All it really needs is a 5V USB charger. -Chuck Harris lop pol
