I've not yet recieved the upgrade mod yet for my ST-70, but have noticed since buying it a few weeks ago, that the power transformer hums. No hum is coming through the speakers, just the transformer itself. It is not running excessively hot, just warm (which Ned at Triode said was a good thing).What may be causing the hum and how might I alleviate it?
Thanks.
Rob
P.S. I'm finally get a taste of tube sound! So far so good. Thanks for all the interesting and provacative reading folks!
