Hi,
This is the schematic of your device:

First of all you will need some mechanical mind to open out the set. The tape mechanism has to be removed and the connections should be noted and removed. If the old belt is already in the mechansim then you will not have any issue with the direction of the belt to go around the capstan flywheel. If you have alreaddy obtained the correct belt then carefully open the back of the mechanism to remove and reset the new belt. When replacing check for the free running of the capstan if not use a small drop of oil to free. If the belt was not there then wind from the motor to the second flywheel after running it around the first flywheel to drag it along so that when the motor turns you have the flywheels turning freely. reset the back plate using a thin probe type tool to hold the belt and release to the motor. For a first time it may be a bit difficult but try again. Hope you get this right. Good day

Ahh, Another Dual cassette deck. These are typically not worth a repair charge. I went looking for a service manual but Hi Fi Engine did not have one but they had a Owners Manual. Any unit that has a specification as to wow and flutter starting new at .18% was never made to be a long lasting deck of any quality. I don't like to be negative about people equipment but you might be better off getting a better deck from the start. If you think it is worth the repair, then send it to someone but I don't think you will want to sink $100 into a unit like this.
I am not saying it is unrepairable but that with what you come out in the end you could have made a better choice for a deck to buy.
It is probably a bad solder joint or bad capacitor on the circuit board.
I am in Chicago and would look at it for you if you want.
