Can someone point me to a source that shows which plugins will work in a 561A? I seem to recall seeing this either in an online manual or other source, but I can't recall where. Thanks! Barry -

Amazing....yesterday they kill 12 of my fellow US Marines and today they try to spam me into thinking they are just good people. Hopefully the boys will show them that while the US Marines can be no

Problem sorted! It *was* the 9V zener in the +50V supply. But at 2am I didn't try fully loading the supply - and if everything isn't connected, the supply goes into burst mode. Eventually convinced

Did you try procedure on page 4-11, step 4? Practically, disable protection circuit by removing two shut down transistors and use Variac to bring line voltage from 0 to about 85 V. Sounds scary, but

Hmm Wonder when we will be getting SPAM from the Vatican ? If Muslim is so fine why do they kill each other as well ? That must be the love thy neighbour bit (self hate ?) Regards Denis Cobley

Does anyone in the group have a Service manual for a Ballantine 6130A Time Mark Generator? Mine "almost" works correctly. The 5ns Sine wave generator (200 MHz) makes sinewaves all over the place. I

Hi Craig I have only worked on a few of these but one trick I found helped was to short the sense pin to gnd - this will allow it to ignore any fault signal and get going. Downside is of course you

Hello Dean, Is MPL a supplier? If so, please, give me the address. Regards Miroslav Pokorni

Well, I bought a 7104 with a known problem. Power supply operates in burst mode (the dreaded tic, tic, squeak, tic, squeak...). So far so good - but this is driving me nuts so I thought I'd run it

My 454 has a minor problem with some 'sticky' controls, when rotated, the outer controls of the Trig level and Horizontal position controls also turns the inner control (HF Stab and Fine

Don't forget "Textronics". When you've worked in a Tek Service Center receiving incoming equipment for repair, you've seen every possible way of spelling it. Dean

Those are called Peltola connectors and made by sliding the smaller eyelet over the coax, folding the braid over it and swedging the larger eyelet over that so that the center conductor is sticking

Your two problems sound unrelated to me. The scale illumination is likely a burned out lamp ... there's more than one. If just one side works and it's working as expected, then the electronics are

Don't ever recall seeing that problem, Hank. Check all your supply voltages, first thing out. If you don't have a manual, you should be able to use one for the 212 if you can't find one for the

I believe the Apple ][ used the 6502 processor. I bought one of the original MITS Altair 8800's (the original S-100 machine) in 1975 or late 1974 -- I can't remember exactly. It came with 256

Folks, I've got a pretty nice RM561A scope with 3A6 and 3B3 plug-ins up on eBay. It's looking for a new parent. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3808108920 Thanks,
