8 mv of hum

Recommended Posts

  A member here suggested I look for a solution to my hum problem on these monoblocks

2a3@250v, -45v@60MA

AC heaters hum adjust

plate choke loaded 6sn7

SE Class A

FR 20hz-20Khz

Input Sensitivity .8v for 1w point-point

 Custom transformers by Electra Print

 I've tried 20 different tubes in all positions and have adjust the hum pots countless times. These babies are noisy so they just sit. Any and all help appreciated. I'm a rookie when it comes to testing voltages. I know to wear rubber soled shoes, one hand in pocket, table is not metal and working indoors. A bottle of my best brandy to a few who help solve my problem. 

            Thank's, MKane
