Here are some guitar amps that I have built. All amps are hand-made using phenolic turret boards, point-to-point wiring.

SE-6V6 4.5 watt single-ended 6V6 guitar amplifier (inspired by the Fender Champ model 5E1)
PP-EL34 50 watt push-pull EL34 guitar amplifier (inspired from Marshall model 1987 "plexi")
