Well, it looks like it's time for me to buy an oscilloscope. But I'm working under a few constraints. In order of most important to less:
1) size. Pocket or USB oscilloscopes highly preferred for portability, so that I can go over to friends' homes to fix their tube amps. Those huge old CRT scopes are definitely out of the question, no matter how well built they are.
2) budget. Would prefer under $100, but up to $200 is okay. Used is fine.
3) high reliability and parts availability. "Buy right, buy once."
4) easy to use
I've seen the pocket oscilloscopes, but they are questionable in terms of reliability. I'm totally willing to give up all but the most essential features/specs in order to keep the size and cost down. Basically, the bare minimum to do amp repairs in the field, but built well enough to last a lifetime.
Worst case scenario, I'll just get one of the pocket scopes, just cause the size is right. Or the DIY pocket oscilloscope, because the price is right.
Oh, BTW, I have no idea of what specs/features are considered minimally functional for repairing tube amps. I understand that many have limits on the input voltage that rule them out. But as I don't know much about oscilloscopes beyond that, I have no idea what I'd need. Please school me on what to get.
Thanks, guys!
