I think i might yank the tubes out of my Ampeg VT 22 guitar amp and use them to build a 2 channel DIY tube amp. My dad has a dynaco DIY tube amp that sounds really good. Has anyone done a similar project? What other DIY amps should i look into? I dont know anything about vacuum tubes..would you have to modify the schematic since i will be using different tubes than the schematic calls for?
