Tascam 644 capstan bearing and pressure clamp This is the roller that's

This is  the roller that's used on the Tascam tension arms

This part maybe common in some other machines but it the first time I have seen them and maybe they only on this half inch model

Here I have listed some reel centres as some people want to just change a centre for making smaller or bigger reels and already have the metal plates

It looks very much like the later M series of mixers so seems they built on the knowledge from earlier

Tascam 644 capstan bearing and pressure clamp This is the roller that'sFrom the Tascam 644 Portastudio I have these listed elsewhere on the site, but people search by model number, so I have listed some like this. Please note, I have seen some of these where I have taken these out, there should be a Teflon washer here, I have seen this missing or its fallen apart. it goes between the spring and the capstan wheel. From this unit and maybe others perhaps the 688
