I got this working quite a while ago and set it aside and am now looking at it again. It sounds real nice except for its running a little bit low, like 31 speed. Im fairly sure it is not the idler due to experimenting. Anyway Im thinking its possibly a leaking diode (and I could be wrong!!!) that connect to the motor. There are 2 Im concerned with but before I remove them the number is 1N1692 which crosses to NTE117. can they be replaced with 1N4007's? I have those on hand is why I ask. They are circled in black in the pic. Thanks!
