mkane Posted November 30, 2016 Share Posted November 30, 2016 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 Quote Link to comment Share on other sites More sharing options...
