The Distortron manual used to recommend running it into a JTM45 for the most authentic "Marshall" sound......The designer doesn't know what amp it's to be played through.
I gotta admit he's right, my JTM45 sounded just like a JTM45, even when the pedal was bypassed.
Just found some PCB shots - 3 TO92's + opamp. I'm guessing it follows the similar JFET/mu-amp/op-amp topology that stacks of other pedals follow, along with a LDR for sag
Any chance you could point me to those pics? I just want a peek.... I'm anxious / impatient.
