I started with replacing all the wax/paper capacitors & large 4 section capacitor in the audio amp.
I used slightly higher rated film caps inside the chassis (factory is 400v, I used 630v)
As I understand film caps are not polarity senstive and can be installed in any direction.
Multi-section can cap was replaced with a unit from Hayseed.
Re-installed the amp and everything still worked great!
