DRBILL Posted April 2, 2003 Share Posted April 2, 2003 I just finished restoring another Williamson (Heath W-4) tube amplifier which included all new caps and tubes and a power transformer (this sounds like making stone soup!). Maybe I'm too sensitive, but there was just too much hum. On a whim, and with a little trepidation, I grounded the unused center tap of the filament winding. Magic! Now my question is why this wasn't included in the original design. Is this going to cause more trouble down the line? Father Bill Quote Link to comment Share on other sites More sharing options...
