How bothersome is it really? As far as sound coming out with the volume control down, if it is just a bit, then the control is probably inexpensive and does not track well. Either replace it with a more expensive one, or live with it, it will do no harm. The question of hum with the tuner off merits a little more research. Does it do the same when the CD player is plugged into this input? How much hum do you hear, what is your amp and how sensitive are your speakers? A bit of hum in a simple tube preamp can be pretty hard to excorcize. Start by moving the preamp to a different position. Changing the lay of the power cords, etc. Talk with other owners of the design and the manufacturer.
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.
