Default Re: Pye T4001 AM TX Modulator

I have no longer any 400/4000 series manuals. I did find my M201 am Olympic manaul. It has the 3 thick film module tx audio board, plus the supplement with the circuit for the later discrete component board.
My Epson scanner printer is currently playing up so will scan when it is ok again. The tx module does take a feedback from near the pa RF output pin.
