Teac Tascam M-3500 M-3700 Meter B PCB 52103011-00

In most cases you wont need a full Pcb as you can chop and change ICs and display bargraphs

etc, and these are available on the site, but for some people they just want to change the whole board , this board has a small connector that has been desoldered off, you will need to be able or your tech to solder the wires onto the new board its though a simple job

This board is the same in both mixers
