Why did you ship before being paid?! I don't know where's the problem in the US mentality about not giving out the bank account numbers. If your bank is so bad that someone just knowing your address

You're right, but it doesn't have to be big, or even a designated capacitor. Mind the parasitics! The CRT with its parastic anode capacitance is enough to zap you big time. Cheers, Kuba

The subject says it, but it isn't fully ot: The C1-122 is a Tektronix 7603 lookalike, the 1st. was the C1-91, the C1-122 ist the 2nd. edition, Plugins have the same connector Pinout but with metric

Hi can anyone help? I require a 0.01mfd 4000v disc ceramic cap C242 for the EHT cct for above oscilloscope. I have tried all the usual suppliers in UK Tried Tektronix but support for this stopped

Hello Stefan, You are right in mentioning the SMPS. For the moment this is the only dangerous circuitry I can think of that is isolated from the chassis. Sorry for the confusion, with "not very

I thought CD4xxx had been on the market by then... what do I know, it's older than me for sure :) >

I connect 1:1 isolation 115V transformer with variac to the out of it and I getting isolation and variance in voltage from 0V up to 150 VAC, again completely isolated from line input.... Should be

Well…look at the Item header: Owners Manual, right? I paid 10 dollar shipping, 10 dollar handling…added to the price. So, what did I get? I tiny half papersize User Reference Guide…. Not a full

Yes the chip design is more than 35 years old. It appears in my Motorola TTL Integrated Circuits Data Book, First Edition of 1971

I've used for years a Tenma "Isolation Transformer", like this one in an ebay listing.

There are variacs that are also isolation transformers. They may be know by another name than variac but they are available at a higher price than the standard garden variety variac. David KC2JD/4

VARIACS ARE NOT ISOLATION TRANSFORMERS!!! VARIACs are wonderfup things and every electronics professional should own one. But they are not transformers in the sense that you are most familiar with. AC

Would the one from a 465 be the same? If so, I might have one you could have. Rick Smith --------------------------------- Have a burning question? Go to Yahoo! Answers and get answers from real

Yes, nothing protects against high secondary voltages, but i expect direct mains power is the main cause for accidents. The i

Hello Stefan, your example is illustrative but not very realistic for my DUTs: usually TEK 'scopes or plug-ins that need repair. Nearly no internal circuits are floating w.r.t. chassis. Another point

Since when was being OLD a problem? (grin) OLD test equipment is very good when it still works and is useful. Because the DC503 is discrete TTL, it is easy to fix and parts should be available and
