Counterpoint SA20

Hey all happy new year ..

I just pick up this beautiful amp this was at a estate sale was only able to plug it in to see if it power up and it did ... So now I buy the unit get it home open the box power it up for about a Half hour or so before I connect anything to it ..

I also had the lid off to take a peak in side all look look .

Now I set my self up connect everything and power it up . I was so please with the sound I was very happy .. so for the first hour it all went well then here is were it went south .. I notice that the right was sounding a bit weak and then the pop and the smoke and no sound I power off look inside the right side went ,,,

Well here is were I ask for help . I know that it can be repair by a few repair place on line .

My big question is who should I use have any one use or had any issue with some of the repairs and experience with some of the repair places .

I would like to repair it or should I sell it with one channel down .

Has anyone had this issues with the Counterpoint ... .

Any help and answer would be nice and thanks to all for the help ...

Be well and Have a Happy New Year ..
