Adcom gfp 565 switch cleaning question

[punkzter]

I was given an Adcom gfp 565 by my uncle. I plugged it in and the volume control was scratchy, which I hopefully fixed last night with some deoxit.

What seems more tricky are the push button switches. A couple of those are also scratchy, but I can't see an opening to get the deoxit in. I've attached a picture.

Does anyone have any advice on how to clean these?

I think its not the switches, just an idea that there is no momentary mute circuit to catch the 'noise'.

I guess that could be it....but only one of the switches is scratchy.

Try going through the front. Remove the faceplate and insert the straw through the spring.

That did it. Thanks for the tip.

That did it. Thanks for the tip.

Reviving old thread. I have an Adcom GTP 500ii preamp with a malfunctioning tone in switch. Can it be cleaned? Does the black front part of the push button come out by pulling? I tried pulling gently but did not come off.
