Model 680 interstage transformer.
#1

Hello  Does anyone know what the D.C. resistance readings should be on the input transformer between the 42 and the 6A3s? I am not getting signal past the plate of the 42 driver tube. plate voltage on the 6A3 s is 290 grid voltage is -63 volts on both tubes. Thanks in advance. Norman
