There are 3 adjustments per side. You will need the service manual. If you have it, please attach.

Here is the adjustment information. If you have not touched the 'protection' trimmers (VR3 & VR4), I would suggest you leave them alone.

I finally found the manual. I had to join another forum to get it. Part of the set says I need a variac. I don't have one. . Any help is appreciated

You do not require a Variac to set the idle current.
Honestly, if the unit sounds good and the heatsink does not get overly warm at idle, I would not mess with it.
Changing capacitors should not affect the output idle current.
