I have a Heath HA-10 Warrior amp that seems to have a hum when I turn on the HV.... I replaced the Oil Filled Cap but it still has the hum.... any ideas? K5DRC Dave, you might try connecting a dummy load and shorting the bias contacts of the amplifier, to see if you get normal resting current on the 811A's. Also, look at the HV reading, and see how much it droops with the bias contacts shorted compared to no load. Have you tested the solid state rectifier in a tube tester, same settings as the 866A. 73, Ed |
