Description

# KT66 powered 1968 Marshall JMP style amp. These profiles are of my own Marshall Plexi style amp that I built in 2015. It is practically a 1968 spec Marshall Plexi circuit but the power section was modified to use KT66 valves. because I only had a JTM45 output transformer. It currently has Genalex Gold Lions in it. Preamp valves are a mix of NOS and modern 12AX7s. The amp can be set to JTM or JMP Negative feedback values, JTM or JMP Tonestacks as well as Valve or diode rectification. I've included a Lite model for those on Pi's, it sounds basically identical to the std one.
