I've done this with a bunch of PNP Ge transistors that had developed internal shorts from tin whiskers. I used a AA battery to drive current thru the whisker and "fuse" it. To do this, you MUST apply

The 556 is the only one I've experience of but I can't remember which tube it uses.

My first recommendation was that you try different shoes. I'd still try this, but if this is happening to everyone, I'd suspect the floor tiles. Some materials are more likely to generate

Hi I have a 164 with some sexy nixies, I replaced something to get it working I cap if I recall correctly. I just decided to order the manual for it, I love the original manuals if I can find them. I

It's used in some Fender Guitar Amps, which explains the prices asked. Dan

Thank you, Dave. I’m wondering whether that 6C10 was used in a production instrument or an in-house fixture. I just checked the web and it commands crazy prices on eBay. Audiophiles have clearly

I don't know which scope used compactrons. I do know a cal fixture sort of did. From my notes: Tektronix 067-0502-01 Amplitude Calibrator. The voltage regulator originally used the 6GE8/7734 signal

I’m curious: which Tek scope used compactrons? Cheers Tom Sent from an iThing; please forgive the typos and brevity

I like the ideas about the anti static heel straps. How can one check the direction of ESD? How to find out if it's me being charged, or the furniture? <CCDman1@...> wrote:

That is HEEL of course

There are anti-static heal straps available. Working with $200k CCD's I'd wear one all day just in case I might forget the wrist strap when coming back from the loo.

OK, I'll try to post again. Try a simple experiment by wrapping a small damp rag around one of your shoes, and secure it with duct tape. Then wander around with the cart and see what happens. This

It's been like this for at least a year (probably much longer) and the staff and other patrons are experiencing shocks too. No one gives a crap It's any time of the day There aren't any other

I suggest a casual investigation to learn from the employees what they might be experiencing. Do not jump to conclusions with a solution or lead them. Just ask if they are experiencing electric

I would investigate that supermarket for proper facility grounding using my Biddle Megger Earth Tester, model 250260. I use it for testing radio station facilities where proper grounding can be vital.

Hi all, I frequent a large grocery market nearby and inevitably every time I go there I get electrical shocks. I walk around with a cart and often if I touch a metal fixture (fridge, mesh rack) I get
