The discriminator coils I already tried and no it's more a hum like 60hz ac and there are no seleniums I put in 1n007 diodes so maybe I'll look into those other tubes for an HK short in them. I don't know where else the ac would come from . It almost seems like a bad cap like powering an old set after it sat for 50 years only the hum is not loud.
