Tascam 644 jack l pcb 52102783-01 they are easy to replace

they are easy to replace just one circlip and they pop out they are same as the A series just black

They used a different one on the early B16 thats with the smaller motors

so why buy from me for 40 pounds if you can buy from him for 35

two are marked with a circle but not sure if that was record or a square

I am not sure if it was the same head on the  E16 but guessing yes as they was all the same format
