RE: hum through both speakers; AC regenerator
Posted by undhilled on August 28, 2012 at 05:59:04:
Hi ET,
Unfortunately, my reported success was premature.
Hum still present.
Tried replacing preamp tubes, but that did not get rid of the hum.
Finally replaced the tube preamp with a Spectral DMC-10 that I have -- hum gone. Any ideas/suggestions why the tube preamp would be associated with hum from both channels? -- it was quiet until a few days ago.
Thanks,
Harvey
