I agree completely ... and its important to pick the right things to learn on.
I have great confidence on anything tube. But on solid state stuff, if differs.

I have great confidence on scientific solid state stuff. It generally has single
digital power supplies, and an analog +- 12 or 15 volt dual tracking supply. AND ... its generally not filled with unobtanium parts nor fragile
circuit boards. High voltage supplies are always quite separate. And the
big good point is that global feedback is generally very simple and
easy to understand. Luckily I never had a 3000+ volt supply go bad.


Not so for my new Indextron ... a nightmare of strange interconnected supplies,
with feedback between them, un-understandable feedback in both
H/V sync and index systems, and unobtanium parts galore. And the
killer -- several unobtanium coils and tranfsormers in the the
area that needs to be ultrasonic washed to get off the corrosive goo.

So I sent it to the experienced specialist.
