Scratchy Sounding Amp / ugghhh

[gyusher]

I bought a MINT Kenwood KM-105 Amp a couple months ago. . .Finally got around to hooking her up today but the sound is scratchy and distorted. I know it is not a source componet or the Preamp or the interconnects.

I've turned the plug over and at this point that is it. . .still scratchy, worse with Loudness engaged. . .At a dead soft idle it ain't bad but add a little power and it is there. . .

Any thoughts? ? ?

Bummer. I've got the KM-206 & KM-208 (150 wpc) and they're decent amps.

Both channels?

Both channels equally. . . I did hook it to my tuner and used the variable output and noticed it being very 'noisey'. . .Thought it was the tuner. Now using my new preamp (matching the amp) it is still there. I guess I can do some little checking. . .I'm no tech.
Both pieces amp and preamp are perfect cosmeticaly. I have to fix it. . . Not expensive and not a critical piece but I like them and want them to work right.

You would think it is the tuner but it does exactly the same thing on all inputs using 3 different tuners and a tape deck. . .

Have you cleaned all the pots and switches w/ deoxit and worked them all 100 times each?
