Wow thanks for the quick response. The table is new with the wiring upgrade. I always do the reconnect dance and usually it has solved the problem. It seems I might need to find a preamp doctor in Alaska to take a look, or try tapping the thing to deal with the humming. I wonder about just leaving it on when I finally get it working properly--it can't cost anything compared to the 2 adcoms sitting there sucking up juice 24/7. I almost sounds like an internal ground is unhooked. I thought I would try to run a wire from the unit's ground post to see if that would work.
apt holman problems
I recently bought a rega 25 and tons of albums -- the good news. The bad news occasionally the right channel cuts out and I reconnect everything and will try some connection cleaner. Now a hum has begun in the phono stage, seems worse on phono 1 than two. I don't have a manual, but might it be a ground issue? Is it worth trying to fix or is it time to get "tubed." Other components are Adcom 5500 monoblocks with Vandersteen 2ce's. thanks.
