Re: Keithley anyone?
I use a 196 regularly and it's my bench standard when doing calibrations on other gear. It the only one that gets a professional cal annually. Rich

Re: Keithley anyone?
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

Re: 6C10 Tube
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

Re: 6C10 Tube
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

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
