Thanks for the hints! I checked the voltages as you suggested. Pin 1 of the 12AU6 is -4.82 volts but pins 1 & 2 on the 19T8 are hovering around + .04v. Also, pin 3 which is supposed to be -.5 v is +13v. Could this mean problems with the caps in the discriminator can?
: Your schematic looks better than the ones on this site.
: To check out my hypothesis, check pin 1 oa the 12AU6 and pins 1 and 2 of the 19T8. Voltages need to be negative. If they are a little different from the voltages shown don't worry about it, but these voltages must not be positive.
: Usually a positive at one of these points is indicative of Silver Mica Disease in the IF transformer in the previous stage.
: Let me know what you find on the voltage measurements. We can go from there.
