aka`s General Shop CX-457f , Multitech TBS-7900 - anyone know the belt sizes? The mechnism is very finicky- I know that when blindly replacing belts, not too tight, not too loose is usually the answer. I`ve yet to get it to auto reverse on record , both sides of the tape. From other sources, many have said that the belt sizes are important to proper operation but did not provide sizes. Can`t find a service manual anywhere. If you can help, many thanks!
