Brian are you breaking things again?

The hum that you are talking about is due to the AC voltage feeding very sensative input gain tube's filement, as we talked, if you get to use the regulated DC voltage of 6.3VDC to each input tube or 12.6 VDC to have them wired in series, this will stop all the hum caused by the AC 60 cycle voltage. Make sure to connect the ground of your DC filement voltage to that of the main ground. You also might want to add another resistor in series to the high voltage in value of 200-300 ohms at 5 watts then folowed by a filter cap of 330-470 MF at 400-450 volts, this network will crop the ripple in the high voltage, it will lower your voltage by few volts, but the outcome is clean filtered DC voltage. Good luck. Ray Samuels |
