I have a heathkit sg-8 that some one has modified
They put a 8 pin socket on the right upper side.
Pin 5 goes to pin 1 of the 12AU7
Pin 6 goes to RF out jack
Pin 7 goes to ground
Pin 8 goes to 6.3 Vac
I ask to find out if any knows of this mod?
If so what tube should I get?
My guess is this tube is amplifying the RF.
