JVC PC-150 boombox belt kit / belt sizes

[ArtCassette]

Tried to look up the sizes / models of the belts for my JVC PC-150 online the other day but couldn't find a darn thing. So I had to do it the classical way -- removed the old ones from my boombox, took the measurements and, factoring in the stretching, came up with the following PMB equivalents:

1) FBS7.0 (main/capstan belt), i.e. 7" circumference, 3 mm wide flat belt, 0.6 mm thick.
2) SBS4.6 (fast forward/rewind), 4.6" circ, 1.2mmx1.2mm square belt
3) SBO6.3 (counter belt) 6.3" circ, 1mmx1mm square belt

Ordered and reinstalled these belts, everything works perfectly now and the playback speed is spot on.

Hope this helps someone.

At one point I was making a note of all my belt changes then I realized that I never do the same one again. I find that there are nuances with very single deck so one may work fine with OG Belts others may need tighter or looser to get the speed and operation correct (auto Stop). When you change belts you should give the speed pot a good back and forth action then set the speed.
