I can't figure out how to post pics on this forum. Can someone help me out?
I am pretty active on the Klipsch Community forum, and I posted a couple of pics there.
Question: I have a little hum at idle, more prevelant in the left channel. Not noticable when music is playing. Is it anything to be concerned about? My speakers are very efficient,(very modified Khorns-105db/watt) and tend to bring out every little thing. I have some Mullard tubes ordered for the VTA board, plus a Weber rectifier. I'm thinking of ordering some re-issue Genelex KT-88's also. I'm hoping that new tubes will lessen the hum at idle. I also noticed the hum is lessened if I put my finger on top of the 12AT7 tubes, especially the one in the center. Is this normal or do I have a ground issue, and will tube dampers make a difference? Thanks for your patience with me! Kevin
