Panasonic of course. Technics only used their own parts (technics is a brand name of Panasonic).

For an audio application you need low esr electrolytic capacitors.

Hi,
I think if you unsolder the capacitors the board will come out. Use a solder pull to unsolder the capacitors.

Hi,

If ain't bust don't fix it. I doubt they'd have any readable
markings if you got them out of the potting compound.
The amp should have a pair of the twin capacitors.

rgds,
