KM 64 schematic
Author: Charlie Brewer
Date: 10/06/2011
I'm repairing a KM 64 that had a noisy AC701K. After replacing the AC 701 with a NOS spare, the mic stopped
working. I reinstalled the original tube, but still have no output. I've searched all my files and have no schematic
for this mic. Filament voltage is present @ 6.0 vdc, plate
voltage is 120 vdc. Do you have a schematic ?
Thanks,
Charlie Brewer
