Though I use a POD for recording(it's only because I can't crank my beloved tube amps at home), I have become a tube snob. As we all know, along with owning tube amps comes maintenance, and an occasional repair. I would like to know where to start for learning how to do this on my own. If I can ever find the time, I'm going to try to take a basic electronics course at the local college. But, besides that, where and how can I learn about tubes, tube amps, and maintenance and repair for them? What are some basic tools I will need besies the obvious soldering gun? Thanks for any help guys!
