I've been trying to repair the notorious 'caution' error on Aiwa HD-S1 (bought it second hand). took it apart, cleaned a bit, but it didn't help. the small rubber belt seems ok. but later, I saw some videos, there seems to be another, much longer belt on the underside. I think that one disintegrated. anyway, what is the exact size of the two belts? thank you.
I've managed to open it up enough to take the belt off. It required quite some de-soldering The rubber belt seems to have 'teeths'. Its a bit loose, dunno if it has ever been replaced.
Here's the service manual https://www.manualslib.com/manual/3332784/Aiwa-Hd-S1.html Owner's manual https://archive.org/details/manual_HDS1_OM_AIWA_EN I can't find any belt sizes on the internet, it's such a rare player around here, they didn't want DAT unless they had copying restrictions, by then CD took it's foothold.
