Hi all. Long time lurker, first time poster.
I've had this amp now for quite a while. I enjoyed it a lot for about ten years then it developed a problem and now it sits looking at me every time I'm down in the shop. Once it warms up the music is replaced by a loud squeal/shriek type noise. Is there a chance that a "re-cap" could solve this issue? I am going to make some room on the bench and make a list of all of the capacitors in there to order and look for any bad ones or other obvious signs of a problem.
It would be great to hear this again. Its been sitting for probably 20 years now. I hope its not just a paper weight
Any tips would be greatly appreciated.

You could power it up and take a look at voltage rails to check PSU capacitors.
Electrolytics usually age and can change value.
