Hi,
I'm new here so if I'm not supposed to do this, sorry!
I have a Heathkit IO-18, which is a 1968 vacuum tube oscilloscope, 5 mHz bandwidth, non -triggered. It's not something you'd want to make measurements with, but with playing around and just getting a start on electronics, it'd be ok. It's a single channel, un-triggered.
I've fully restored it, replaced all the caps and checked all tubes. It is safe to use and is clean. I have around $50 in parts, plus about 10 hours of work into this thing.
I also have a hp 54200 digital oscilloscope, 50 mHz. I'm not sure if this works. It's missing the cover but is clean. I tested the CRT, the most expensive part, with a Sencore CRT tester and it test good. When working, it's a duel channel. I have to warn you, it might be a challenge to fix this, or it might be stupidly simple.
If you have no other options, these might be ok. How about $40 plus shipping for the Heathkit and $25 plus shipping for the hp? I live in Connecticut, 06033.
