Hello,
My question is similar to this one and the board also seems the same, so this might be the same answer (an H model). So it seems multiple boards, only a hand full of cases (V3 this one).
There is an extra capacitor on the back and I think some later soldering on one of the IC’s which might indicate a repair.
The pot reads 1378048 (1980 week 48), and there is a difference with the original poster’s board that it has an extra TCI-A4H 94HB written on it.
I will add some pictures, but I didn’t take the unit completely apart to get an image of the top of the board.
Regards, Airell.
