Re IO-4510 scope

[Murray Grandy]

Thought I would give an up-date on subject scope. I'm a slow worker. The scope is now working fine as far as I can tell. I was able to get .015 6KV capacitors from someone at Cal State. Mouser and several other suppliers did not have them. I ended up buying a sack of 50 just to get 4. As for the 3KV diodes, I did replace them with NOS ones from Randy. ( Sorry I have forgotten his call, I had a hard drive fail and lost everything). For what it's worth, I found I had a DVM with 200 MEG ohm scale (most meters I have seen only have 20 MEG scale). Checking the Hi Voltage diodes on this 200 scale showed the old ones had a forward reading of 20+ meg. The new ones had a reading around 12+ meg. Don't know if that means anything, but thought I would pass it along anyway. The scope does work without the 3KV supply, but the trace is much, much brighter with the 3KV connected. So, anyone need .015, 6KV capacitors? I have about 40 that I can do without. And again, thanks for all the help with this problem.
