Hi all,
I was cleaning out the room over the garage and dug out the old Kenwood KA-7002 amplifier my dad gave me as a kid.
I used to use it as a sub amp, but I haven't used it in a long time, but it used to work fine on both channels. I hooked it up and sound only comes out of the right channel. But, if I turn the balance all the way left and turn the volume up 2/3-3/4 of the way it crackles some and then the music will come in, following the bass hits (but it's crackly). If I rotate the volume knob back and forth with the bass it seems to help a little. Sometimes it will break into working full-time on the left channel for a few seconds, but then it drops out again.
If I press the "null balance" button, sound comes out of both speakers OK.
I have tried switching inputs (moved RCAs from input 1 to input 2), and tried different speaker outputs (tried on A and B independantly), but nothing changes the problem.
I tried some contact cleaner spray on the volume/balance control, but that didn't seem to help.
The heatsink on the left side is barely warm, while the right side is more so (normal temp?).
Thanks for any hints/suggestions,
Mike
