Horrible screeching sound - why?

Hi, it’s a Bose Wave radio/cd player I have, but the model didn’t come up, so I had to choose this category. It has some scratchy sounds emanating from the rhs speaker, then it’ll play cd or radio for about 10/15 seconds, then it starts a dreadful screeching sound that curdles the blood and I have to pull the plug out quickly. Does this sound repairable and if so, is it a beginner’s job and what parts would be needed please? Thanks for any advice.

I have the same issue. The question does not seem to be answered. I will check for any leaky or bulged capacitors. It will be a few week before I can look into this. Hopefull the Solution is to replace. Andrew S is this something you have solved? How do we get and replace the capacitors?

@bearsel This is not something I have solved yet, merely a guess based on the 2000's capacitor plague. If the capacitors seem to be blown and/or check bad on an ESR meter, we can use the brand, series, and dimensions to find equivalent capacitors on DigiKey, Mouser, or another distributor with cheaper shipping to your area.

Can you open up the radio and check for any leaky or bulged capacitors? I have attached a picture below.
