I can't find anything other than lightweight square belts anymore. My original is 1.67x1.67mm; so far I've found nothing even close. Got any hints? I'm in the US. Thanks.
Thakker in Germany https://www.thakker.eu/en/belts/ has a great selection. He did stop exports outside of the EU early in the covid outbreak not sure if that still applies.
In Australia Wagner Electronics. They don't have 1.7, but have 1.4 and 2.0 square section. Sometimes going slightly thicker improves performance (CD drawer loader, for example) and lasts longer. However a belt the wrong thickness can affect pitch is it's a drive belt for cassette or turntable.

Go through the Condor Audio site, he is an Israeli guy who does audio restorations.
He mentioned a supplier in Texas, but it was long back.

For some reason., I cannot access AliExpress with Firefox in India

...if you want a load of rubbish belts. On the other hand, if you want the unit to work properly don't bother with Ali... I have bags full of Ali Express belts given to me by clients who thought they were being helpful by saving me the bother of sourcing parts for their repairs. IME they are worse than useless.
Measure it, get O rings, Nitrile or Viton, from a rubber parts supplier near your place, even get at hardware shops. Hydaulics parts use O rings, so do cars and tractors.
The section is self wedging with a better contact, O ring should work.

The optimum angle between the pulley sides for grip is different for an o-ring than for a square section belt. The angle of the 'V' for a square section belt is 90º, whereas for an o-ring drive the optimum is <90º depending on the material the o-ring is made out of. A square section belt in an o-ring pulley will 'pinch' as it runs through the pulley, generating high frequency noise in the belt, whereas an o-ring in a pulley meant for a square section belt will not be able to transfer as much torque as the correct pulley. Stretching the o-ring to increase grip puts more lateral load on the pulley bearing, which leads to increased bearing wear.
For critical applications (e.g. turntable motor pulley) o-rings and square section belts are not interchangeable without some degradation in performance. In other applications YMMV.
