Tascam 112 112 mk 2 jack pcb 91552103-02 or 52103648-01 Style:91552103-02 and many many others there

and many many others there are some variants so the best way is to look at how the holes are to find the one you want here is 2 holes at a slight angle punched in the main frame

and these are available on the site

its a one piece unit but easy to replace

this unit does goe wrong but its very easy to swop

Two boards from the A4 they are identical but have different colour molex plugs
