Hi Doctor
I am really pleased with the diagrams , do you have the schematic with the pre-amp on please ,it is part of the same board as the power amp occupies but not shown on the power amp schematic .

The preamp is there.

It is all the information that is available from Marshall.

Thanks it has already helped me find the problem with my amp. ( a bad resister on the emitter of TR14 causing the high side to be permanently on) it makes a difference
when you can see what's going where .

thanks again
