what would a good true tube headphone amp project be that has a layout, kit or something. I've built a few hybrid amps but the most I've done is 12 volt supplies. I'd like to move away from that and make a desktop amp with more serious plate voltage.    thanks

hi my name is Will and I'm new to head-fi. I'm a 32 year old electronics tech that's pretty much here for the diy stuff hope to meet some cool people and check out some interesting circuits. This was my last headphone amp I built.   ...
