Here is an amp that I built for myself, a Tribute to the early days of Marshall. It's a 10 Watt 6AQ5 power section dual channel amp. Flip the left switch to the right and the preamp is a JTM45 Normal channel Hi or Low, and toggle the right hand switch up and it's a JTM45 Bright channel Hi or low input. Flip the left switch to the left and it's a Bright channel Plexi Hi or Low input. The power section is cathode bias, built with all of the good parts, ClassicTone PT, MPS OT, ClassicTone choke, pec pots, mustard caps, Draloric resistors, Cliff jacks. For the record, I've never put another makers badge on an amp, but since this is a tribute to the glory days, I allowed myself that one time. And the amp stays here for my personal use.
