Teac Tascam M-3500 M-3700 input B pcb 52102991-01 52102991-02 and -03

One of four Pcbs in the M3500 it has a habit of going wrong, if some wants just an individual switch I can break a board down into parts but its probably worth buying a whole board as who knows what switch may go down next

I have now 3 though I guess they would be able to be used in same situation

Let me know
