I’ll pay more attn next time before desoldering. It’s been easy to recap till this snag…I REALLY appreciate ALL replies.
BTW the problem with the unit is the left output goes dead after a period of time…short. So this is a hit and hope repair. Dont have the advanced skill to determine actual failing piece.
It looks like this capacitor is still available:

At least, that's what the "copy link" I clicked on gives... I'd just post the .pdf here, but unsure if that's OK.
Look at the PCB and see if one of the pads for the cap is square and one round. Look at the existing caps on the board to determine if the square pad is plus or minus and they all will be that way.
Plan B is to get a 22uF 50V bipolar cap and use it there, then polarity becomes irrelevant.
Just as blind as you, but there must be some reason, tons of regular electrolytics are used elsewhere.
Plus it´s not doing "regular" duties such as rail filtering, audio coupling between stages, cathode/emitter caps, etc, but coming straight out of a "mystery" IC.
We don´t even know what´s passing through it, might be Audio, might be some clock/switching frequency, who knows?
But a bipolar should work there without trouble.
