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?

Right. Always pay professionals. Never do anything yourself. Above all never bother to learn how anything works. Brilliant strategy.

Og cold. Og try find fire builder. Og find no one. Og not try. Spark might hurt. Og go back cave, shiver dark alone.
I, like you, have no idea of what would need to be fixed, so I send all my tube stuff (and SS stuff) to Ralph Karsten at Atma-Sphere.
He knows his stuff and his recent work of finding the source of a buzz was priced so low, I can't believe it was worth his while.

Actually I didn’t mean for this to come off negative and rereading it some of it does. Sorry!
Just meant that a lot of people would like to be more DIY with their tube equipment but don’t know where to start. I was just wondering if there was a way learn to do it, do you think people would be interested?
