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

Hi All, Two questions: Anyone heard from Deane Kidd recently? Is he still answering e-mails (vacation?). I am looking for an HV multiplier for a really good 2235. If I cannot locate one at a

i dont believe that vhs tapes will die off that quickly

am radio is still very much alive. maybe NTSC will take a similar course???

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

Well, what fun would it be otherwise? Heh... Would be nice if someone could X-ray one of those puppies to determine where the cell actually is. But the equivalent part numbers are even more useful;

Remember that cable will no doubt continue to supply NTSC VSB-AM TV for some time into the future in many markets. Too many retro folks don't have ATSC or QAM capability and many of those folks will

Hi everyone, This is my first post to this group. I build DIY audio for myself and the more I read/talk to individuals it seems like an Oscope should definitely be on my list of things to purchase.

Be very careful here. There's a reason the Postal Service will not even ship Lithium cells and it is illegal to ship them via air cargo. If you happen to dremel into the cell, not only are you getting

Yes there is compensation circuitry, but this is mainly before the gate and not adjustable. I measured the bridge signals at the + and - nodes with 600mV SW input and no triggering (and shunt resistor

Hi Michael, If the relay is opening again after closing, it is not getting coil voltage from its own contacts. If you burnish (clean) the relay contacts, it will probably hold in until the power

Be careful, the CRT heater gets its supply directly from the big mains power transformer, *not* from the HV transformer. When the isolation is bad then the HV won't start. See many earlier posts about

Hi Chris, I used to demo the 492 as a "receiver that looks like a scope". This made it much easier for the average person who was not familiar with spectrum analyzers to quickly grasp how it worked. I

I picked up a cheap 541 last week which worked, but not very well. The fan had broken free from it's mounts and was sitting on the chassis- I had to beg the guy I bought it from to please turn it off,

This appears to be true with respect to all NTSC test equipment. I have a ton of signal generators and various NTSC monitors and I wonder what they will be worth soon with digital TV coming? Kinda

Greg, Thanks for your good suggestion. The signal at the input of the trigger generator looked great and I assumed the balance circuits was okay. I checked the adjustment for trigger balance and found

I tried again. Since the CRT is completely covered I cannot see any filament working. Shortly before the tube's diameter gets wider some connectors for deflection I guess. Even there some color avoid
