I'm having trouble tracking these down. I'm racking a pair of 35102s and I need to know where to best access the line transformer to separate it from the mic input.
Check with Peter Purpose if he have it scanned! Mine is huge!
Switching is provided with a relay controlled by the gainswitch!
Just desolder the cables to pin 2 (+) and 5 (-) on the T1448 line in transformer and solder in your line in to these two pins! Pin 27 on the back connector is the line in primary center.
