Has to be at least a tripler with 6kV diodes and 10nF caps/10kV each. For a tripler - 3 diodes and 3 capacitors... Greg

Jerry, you welcome. I see you probably used R186 trig bal to adjust voltage. that -3V was probably coming from out of Q190. good job, Greg checked good

Would anyone have a copy of Stan Griffiths' Book "Oscilloscopes: Selecting and Restoring a Classic" they would be willing to sell at a reasonable price? Please reply to me off-list. Thanks in Advance

These scopes have similar CRTs: SC501 (PN 154-0699-00) MR501 (PN 154-0703-00) 212 (PN 154-0699-00) 211 (PN 154-0642-00) In my 212 manual the CRT circuit shows .6V AC (that's POINT SIX VOLTS) coming

Hi from Deane: Yes, I am still alive and well and still rather sarcastic as follows. You want the HV multiplier from the 2235 scope but you don't include the Tek part number. Yes, I can go find the

I was originally going to suggest one of the T9xx scopes for portability and really low cost, but there are no expansion options at all. The 5000 series scopes are cheap and have a large CRT, (and I

Hi, Paul, * REPLY SEPARATOR * The 7B85 is easily usable as a standard timebase. It was, as I recall (someone check me on this?) designed as a 'companion' unit to the 7B92A to

I just recently bought one of these for my 7603 mainframe scope, are they suitable as a general purpose timebase? I'm not rally familiar with the capabilities of this particular plugin, though I am

Stephan, By taking your time and watching for sellers with good feedback ratings. Buying through Ebay can be a very good way to go. Tektronix 465's and HP 1740's are great oscilloscopes with 2

While it's true that you don't NEED a 'scope with a bandwidth of several hundred MHz for audio range use, I'd have to agree that a 7000 series 'scope is an excellent choice. They're versatile, very

I have (most of) a tektronix 212 scope that has been damaged badly, and I'm not going to try to fix it. What I will be doing is salvaging the CRT and building a new scope around it. I am looking for

for just doing audio work you dont need a 350 mhz scope look around for something like a t932 or 2215a. "group please respond"

i received an enail from deane last night. are you sure the tripler is actually defective? the tripler in the 2235 and similar scopes is quite small so an nte528 tv tripler cant be easily fit in as in

I'm part of the minority that gets my signal off the air. The signal has gotten much worse over the part few years, I think the providers don't want to maintain the equipment anymore and are just
