Taito Stereo Amp K91X0799A

[markedkiller78]

I’ve got 2 of these amps, but can’t find any documentation

I can take a guess at

P(4) = Power
S1 = stereo in
S2 = ???
S3 = speaker out (it’s the same connector as the type X zero amp, but not necessarily the same pinout)

Has anyone came across this amp before?

S2 is possibly 12v + ground? ignore me I missed the p for power

I’m guessing Geo, based on the thickness of the pins and there are 2 brown and 1 black wire

Wouldn't be mono in would it?

Start looking up datasheets of the ICs on that board and what connectors connect where.

Power is easy enough to verify.

There's no way to control volume on that board?

No, the type x zero (egret 3 drop in) is the same
