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

Peter, thas is an MMC which is a 4000 series cmos IC that is equal to the CD4053. The MC4035P is a motorola "only" IC, much older with no equivalent as far as I know. Luis ct1dmk

Here is a datasheet for it: http://www.datasheetcatalog.com/datasheets_pdf/M/M/C/4/MMC4035.shtml Ciao Peter http://home.pages.at/pullrich -----Ursprüngliche Nachricht----- Von:

I found on my 2467 that the connections to the CRT plates are very close to the holes in the metal chassis to pass the wires through. I had to bend mine slightly to fix an intermittent problem

Luis is absolutely right. I am pretty sure that the design of the DC503 was before 4000 series of CMOS was invented. I did find a referenceto the MC4035P. It was described as a quad 'D' type latch

Correct, The MC4035 is NOT a CD4035 (the MC14035 is a CD4035). luis c. ct1dmk

Would the Mot equivalent for a CD4035 not be MC14035, as opposed to MC4035? same). On Behalf

I have a CD4035AN if you want it. I can't tell if it's the same as the MC4035P (the pkg should be the same). Here's a data sheet for the CD4035 if it helps you sleuth it out -

George, Can you tell us which counter? John ________________________________________________________________ Sent via the WebMail system at aztec-net.com

I could tell the story of how I blew up this previously working counter by plugging it into a TM500 frame with some rear interface wiring and a broken key, if anyone is interested in a cautionary
