This is the left channel of my Bartolomeo Aloia ST-140.

I'm going to replace the electrolites as they are in the 20 and it's clear they have reached the end of their life.

I plan to upgrade the big cans from 4700 micro to 5600 (chemi-con kmh) while the others will remain of the same value but I'll look for low esr components (panasonic FM or FC) in the supply line.

Have you got the service manual to set up the bias and offset voltage to the correct value afterwards? If you haven't or don't know the values, I would advise against doing those mods.

Unfortunately, I have no access to these information.

Are you suggesting to keep the original value of the big caps or to avoid to change all caps?

I can clearly hear the caps are close to their life and keeping it as it is it's not an option I like.

Thanks for the input
