Thanks for the reply Harvey. I have a Mouser order in so I'm just going to replace all of the HV components and hope the transformer didn't get toasted. One of those HV caps has a suspicious

" Your idea is correct, the large belt driven compressors are the best and places like Harbor Freight has them brand new for a reasonable price. " Yea, I have been tempted a few times to use the 25%

The SG504 shipped with the levelling head. But because it was not captive, and many of the SG504's came from factory closures, the inventory sale folks too anything that looked like a cable and threw

In my earlier email, instead of "calibrate", I should have written "adjust". DaveD

The Tektronix service manuals for these older ‘scopes contain lists of the required (or at least recommended) test equipment needed to calibrate the ‘scope in the service section of the manual. In

David, look at what I did to add to the confusion by writing "signal analyzer" instead of signal standardizer... A small positive contribution: The SG504 does indeed not level without a special

Nice "shopping list" Dave! I'll save it for a latter date, but first I must expand my space, 3 rooms aren't enough! Thank you all for sharing information with such attention to detail.

Your idea is correct, the large belt driven compressors are the best and places like Harbor Freight has them brand new for a reasonable price. Don't forget the water filtration and drain the water

O man, it's still early over here and I already make the silliest mistakes: The first line of my recent message should have read "The 067-0587-01 that you recently acquired is what Tek calls a *signal

David, The 067-0587-01 that you recently acquired is what Tek calls a *signal analyzer*. An *input standardizer* is a small module that is used to standardize the input impedance of 1 MOhm 'scope

Did anyone else notice the out-of-sequence problem I think I see? I've seen it before but it seems very clear in this exchange. I've responded to a few posts as a web-reply through the link directly

" Because they don't have a "quiet" air compressor. " That's the biggest problem. In the garage, I built a compressor dog house with six inch walls with insulation on all side. Even the access door is

this is such a timely thread because of my current need to get my four 7000 scopes calibrated and the fact that I managed to acquire the input standardizer as the first part of my quest. Upon reading

After reading your email Harvey I went to see what is available and I agree, it would be nice to have it also. I need to slow down, I would spend myself into a hole in the ground! For some reason I do

Nice details Ben, thank you!

WOW what a nice reply Harvey! Thank you very much! You swiped me off my feet with all the details! OK, I knew I was over my head, but now I think I'll start at -100th floor and work up from there. I'l

Sorry for misspelling repetion three times... Raymond

That's not correct, Harvey. Just took some "measurements" with one of my TG501's. At 1 ms repetition rate, the needle is formed by a rising edge of about 30 ns, decaying in about 120 us, so that (most
