So I'm looking for a project that my son and I can work on together. He has no interest in music or guitar stuff at all, but is showing an interest in learning about electronics in general (he's 13). I thought that an old tube amp has a relatively simple circuit and that it would be a good project to learn from and I would get a tube amp in the process! I don't know how realistic it would be (I have some basic understanding how to solder etc.) but I would like to give it a go. Now the catch is that I don't really have the funds to just go buy a kit, so I was thinking about the possibility about salvaging the components from old equipment. I have a couple old solid state amps (I can build a new cabinet) but I don't know what would really be feasible as far as harvesting parts. I'm assuming it would probably be best to buy new capacitors, resistors etc... I have an old reverb tank, some speakers, wood for a cabinet. Maybe a possible chassis... I guess what I would need is a power transformer, tube sockets etc... Any suggestions where to find these things for very little cost? Is there anything in an old solid state amp that I could repurpose for a tube amp? I would like to build a vibro champ reverb if at all possible, but I would be happy with just a champ circuit if it makes it easier... I know there is a ton of info on this forum and trust y'alls knowledge... any thoughts would be much appreciated, and thanks in advance!
