Hey guys.
I replaced the output tubes in an ECL86 amp with PCL86, but in order to do this, I had to install a separate transformer to get the necessary heater voltage.
The transformer's two output wires are twisted tightly, and directly connected to the PCL86's heater pins (4 and 5), and the hum is aggressive.
I assume I am doing it wrong, but I'm not 100% sure on how to rectify this. Other than literally rectifying it to dc, that is.
Am I supposed to connect one of the output wires to ground?
