What is the Philips model# for the floor/console mount cassette player/recorder, I'm looking to find the part# & or size for the 2 SBS series drive belts, opened up one I purchased recently & started poking around to get familiar with them, the belts are goo & I'm sure the other ones I have will need them also,the fast forward/rewind drive/idler wheel rubber is split also,provided 12v power the solenoid engages & the record light comes on,jumpped out the motor & it runs fine,plan on making a test type bench to fully test them with a radio & speakers.

This isn't going to help right away but this is where to get the belts and anything else. Not sure of the size of the belts right off hand but BigMoneyLewis knows. Hopefully, he'll chime in on the size of them.

bump any one BigMonyL

o-rings...?? would they work?

Buy these on eBay. I purchased these and installed them myself on my nos cassette player because the originals didn't look healthy after 46 years. Tested the unit and it functions perfectly. A little tricky sneaking them in there and onto the pulley wheels but with a little patience, it's easily done. Pick the two that are closest in size to your originals or pick two that don't fit super tight, just good
and snug when on the pulleys. EBay number is 162126752738. Hope this helps.

Here ya go:
