Hi, I need your help, I have a Betamax T7 video that I want to change the belt for. You can watch the tutorial video.

Do you happen to have a list of the belts used on this machine? I ordered some for a complete replacement and the two smaller ones I received for the threading assembly are too narrow compared to what I see on it.
