Hello i have an akai 1730 dss quadraphonic reel to reel
in good condition, but it doesn`t pull the tape.
you have to pull the reel with the hand to begin
to play.

Thank you in advance

Hi gp37,
There are normally three potential problems with the old Akai R-R units.

1.) The grease has dried - clean the old grease and relubricate.

2.) The belts are "worn" - find replacement belts from a second source.

3.) The micro switch contacts are bad - Replace, they are a standard item.

Other things to look for are worn bearings, the capstan bearing is critical. A bad pinchroller is trouble. Sit it on a table or clean flat surface where it touches the tape. There should be no gap in the center. You can get away with a very small gap. Watch that the entire tape path is clean and not worn. DO NOT ATTEMPT to correct the head alignment - ever, unless the heads show zero wear (are new).

Good luck with your repair!

-Chris
