How many people wish they could maintain and/or service/modify their own tube equipment?


I know many people attempt to repair and/or modify their own tube amps and tube preamps with poor results. They don’t know what to modify, how to troubleshoot to repair, have poor soldering ability or even just how to maintain it. My question is if you were able to have someone teach you on-line one-on-one via Zoom or Skype would you want to learn to do it yourself? Do you think this might be a good idea in these troubled times? What would you be looking for?

Some shouldn’t ride Harleys, or Skydive.      Some should never pick up a hammer(for any reason), or soldering iron(near tube gear).      Some things are harder to get killed with, than others.      Gravity and high voltages, can prove very unforgiving.      Then again; the only people that never fail, are those that never try.      AND; there’s only one way to learn self-reliance.      The competent generally aspire, to rely on themselves and are willing to learn(yes: they would be interested).
I will do maintenance such as replacing tubes, bias adj. and simple repairs like a switch, lamp, bias resistor, etc... but if I can't easily troubleshoot I will send it to a pro or ideally where it was made

Fortunately I have excellent soldering skills.  I started working for my uncle at 15 .   He used to make black boxes for cable and I would remove the PROM and solder in a socket so he could burn the descrambler PROM and plug it in.... I got "paid" with black boxes.for the work . I kept a few and sold a bunch.    I have been into RC for 30 years so that soldering skill was handy.  I also solder routinely for work where we use a Pace rework station.   

It's a skill that's easy to learn but takes a while to master ,  with the right tools and some practice anyone can do it

I should add that you need to really be careful with tube amps because the internal voltages are lethal.....
