Tascam Ministudio Porta One Porta Two roller tyre GEC transport

I have tried to repair machines using some other manufacturers wheels tires etc but they just don't work too big too small etc

I finally had to have them made for me

I have had these made for the two machines , they use the GEC transport, some of the other  Portastudio units use the same transport, but I have not checked if these wheels are the same yet.
