Title: 36 watt half power switch bias voltage question Post by: jdandry on October 11, 2016, 07:47:16 PM Built a 36 watt. with the half power switch on I am getting almost 75 volts on the cathodes of the un-used power tubes.
Is that normal. On the two tube running when the half power switch in on..the bias is correct. When I have the full power mode on, the bias is correct on all 4 tubes. Is this how it is suppose to run? Thanks |
