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.
