Which tuner to get and getting the most from it. Thank God, for the radio!

RE: Bose Wave Radio/CD - Scratchy Noises When Off

Thanks! Caps are easy, and are on my list of top suspects. However, I am getting no audible hum or buzz even with the radio on. If you put your ear against the speakers, with the volume at 0, you can still very faintly hear the music (but zero hum), but when you turn the unit "off" the music stops (and the scratchy noise starts), so there is a difference between "on" and "off".

I'm also thinking the issue is somewhere else - the output amplifier is misbehaving when it's partially powered off, or the power supply itself isn't fully off when it needs to be (letting small voltage spikes through to the amplifier). Or something else, who knows?

I am totally guessing at this point - without a service manual, it's all I can do. The radio isn't worth the cost of replacing parts till it works, so if the fix isn't simple and cheap, the radio will probably go back in the trash. If I figure it out, I'll post my results, in case it helps someone else.
