Tascam 234 sw pcb a and b 52101202-01 52101203 -01

The Tascam 234 was a rack mounted unit,  and is becoming popular again

Its basically a cassette reel to reel, still very popular and sell for a lot now and I see that price is rising.

This is  dual marked pcb and a second pcb , if you only need a switch, I will consider breaking one
