TASCAM TEAC M-3500 M-3700 RETURN B PCB 52102997-00

PCB From the M-3500, M-3700 be careful to check the board name and number on the rear as some here have same board name but different rear pcb numbers

I  have seen this board is the same but they have ringed with pen effect 2 or 4 i think its just a link change on the board but please check a if i have it will send what you need
