This is a Fisher PH-480 boombox. It had a left side channel sound problem. I spent many hours to find out what was causing this issue.
I was able to check 3 of PH-480 boomboxes and found out that all of them had a similar type of sound issue. After the countless test and error process, I concluded that all of 3 had the same reason for its different type of sound issue.
The tone control board.
So if you have a Fisher PH-480 and need to fix the sound issue, most likely the problem came from the tone control board. So here is my two cents, whatever you do to fix the sound issue on Fisher PH-480, you want to start with the tone control board.
Enjoy my another nightmare of the restoration work.
