Tascam 22-2 22-4 X-3 x-300 and other 1/4 inch left tension arm
From a scrapped 22-2 but I guess is the 22-4 and maybe some other models, sometimes the grease on these cakes up and it gets stuck or someone bashes the machine and breaks the pin at the end.
I am selling just the arm though from time to time you may get some extra bits with them if i have them, springs etc
I am not sure what the white bit was in the photo as it was a long time ago, I will include if I have otherwise its just the arm
