That's great, TerraHertz! I can wait until you have time to scan, no problem! And I can also "stitch" the scans together and repost the schematics here, to relieve you somewhat from the tedious work.
About model numbers, I think V-202 is just like the V-352: V-202 is the 20MHz model, while the V-352 is the 35MHz model. Looking at the mechanical drawings, they look quite similar, but later I'll take a picture from mine and post here. About the F suffix, I have no clue what is means, but I hope it's a minor revision, with compatible guts (and schematics).
Thanks for talking about the common problem with the gain switches, however I think mine has problems in the high voltage circuitry, since the previous owner told me the scope had no image on screen, and he claims to have tested high voltage presence on the "multiplier output" (his words), but found nothing. To tell you the truth, I still didn't try to power on the scope, I want to dismantle and examine it in detail only after getting the schematics, I don't want to blindly disassemble it, running the risk of making a fatal mistake.
I have no experience with CRTs and analog electronics, so I want to read and study everything I can before going for it! That reminds me of another question: I just removed the main housing to examine the internals, and I saw no apparent flyback in the scope. Does this model use a flyback? Or no? And is there a way to test the tube to check if it is still good? My main fear here is that the tube gone bad, because it will be very hard to find a replacement if needed!
Thanks a lot!
