It's time to send it back to the manufacturer or a good tech for repair. It does appear to be a power supply problem of some sort. It seems unlikely that you will be able to sort it out yourself. Marakanetz idea will be inexpensive to try and will be an enhancement even if it does not fix the problem so it will be a good idea either way. Please report back with the resolution.
Problem with preamp..need direction.
I have a cheap audcom 2 tube/remote pre w/auricaps.
Im getting music out of the L channel with the volume all the way down.It does it with the tuner,sacd player and phono.The R channel is quiet.
If there is no source of music (turn the tuner off) I get a hum from the L channel.
I have switched the tubes around,installed different tubes.No fix.
I switched the speaker cables in back of the amp and then the problem goes to the R channel.
I switched the I.C.'s in back of the amp....then the preamp and the R channel stays affected.
I guess this narrows it down to the preamp.
My question is "NOW WHAT"! I have soldering skills but thats where my tech.ability/knowledge ends.
I'd like to be able to do a DIY fix if possible.
Thanks for any help.
