TASCAM 688 MONITOR B PCB 52101678-01

The 688 was really the flagship analogue portastudio amazing what the could get on 1/8 inch tape

I was amazed how heavy and how big the machine was must be 15 kilos maybe,

Nearly all the boards inside are with connectors so its one  that can be serviced easier

I have seen 2 versions of this pcb
