Marshall Lead 100 MOSFET
Reportedly didn't sound right. This used a differential i\p MPSA06's with a voltage amp transistor MPSA93 driving the MOSFET's direct. Checking the transistors I was dubious about the over current limit transistors (BC182\212) health so replaced them with (BC546\556). All the pots were switch cleaned as they were noisy, okay after.
