[Kenwood] TS-850AT Tuner Noise

[Darrell Drake]

Hi Scott....
    I assume you never got a reply to your post...at least I haven't seen
one. I have a similar noise coming from the tuner of my 950SDX.
I put out a post as you did and the only reply I saw was from someone who
said his tuner squeals as well ! I really needed to know that! Lots of help
there. Hope you get some POSITIVE replies and they get posted.
