Along with pots/switches cleaning just check all of the fuses...and it has lots of them...the speaker fuses on its rear (might NOT be fuse there, but re-sets instead), but under the hood will be fuses, and also under the bottom plate...ensure the fuses are good, the ends are clean, and the fuse-holder contacts are clean, and always ensure all fuses are fast-blow ones along with being the correct rating.  Also be sure that your speaker wire connectors are CLEAN and devoid of dead insects, etc....the "devoid of insects" thing also applies to under the hood...look everywhere for old insect/spider carcasses....you would be surprised at how well an old insect/spider carcass across soldered connections can short things out to at least some extent! 

Thanks for all the pointers, I will definitely take a look at things and see if I can rule out some of these potential issues.  I want this thing to work like I know it can, it really does sound great.

The it moves to both channels.   I should mention that the volume knob is a little scratchy when it first starts up then quickly seems to smooth out in a minute or two.   Could this be related to the volume knob?      And I will try the Deoxit for sure, never used that before where would I look to buy that locally?

You can find it at a Guitar Center store, or order it on line from Parts Express.

Yes, it could potentially be related to the volume knob.

 

$350 should get you a full recap/restore.

Too bad that RadioShack bit the dust!  I liked their control cleaner/lube for use after using de-oxit to remove all the crud in the pots and switches!

This works after Deoxit as well.

I think he mentioned that he had gone through it himself and did all the cleaning, pretty sure it wasn't a professional servicing if I remember correctly.    I did spend $350 on it, are you thinking that a professional servicing would be about that much?

 

Yes.  A competent and thorough professional service would be $200 - $300.  With the right technician, I woudn't hesitate to invest that much in such a unit.
