The shut down their VCR parts division a few years ago. From my understanding they only kept it open to sell off whatever stock they had left.
Only website I'm still aware of now is SMC Electronics (
www.smcelectronics.com), but even they are out of lots of items (make sure you email first before placing an order).
I was told turntableneedles.com (
https://www.turntableneedles.com/Cam...er_Drive_Belts) stocks some, but you'd need to figure out what size/dimensions you need first.
Other than that, I guess roll the dice with ebay and Amazon.
I would love to hear if anyone knows of any other sites.
