Tascam 644 pitch control pcb 52102780-00 I am going to play

I am going to play with the one I have pulled out as there is a silver ring that I think you maybe able to undo the set screw there and somehow twist that ring around to get some extra tension

there also can be long lead times so you don't want to be without your machine

I do not yet have the Teac part number but will add later

Please note this is an original document

but if you have just a whole there now these are a whole lot better
