Recently plugged my lp3.1 ultra into a new power amp, with more power than the 45SET Firebottle, and the hum is much more noticeable now. Have tried many different tubes in all positions with little change in hum. It did seems like yesterday I noticed hum decreased as everything came up to temp but was still there. Any tips from anyone else on what I should consider doing? I can solder.

I changed the5y3 to a 5u4 and I plugged the power cord into a quality power conditioner.I use highly modified Klipschorns with Volti horn upgrades with bms4592nd mids and I have to put my head un against the grill to hear a faint buzz.
