Hello!
I'm sorry the question says CFD-8, but the site doesn't have the 510 in its database.
I've been trying to fix an old CFD-510 Sony Boombox I found a while ago, everything else works pretty great, but the cassette deck needs a new belt. This is easier said than done, as the idiot who had it before me sealed the access points with a resin. After a LOT of rubbing alcohol later, I can peel back the access point, but there are things in the way, and I can't figure out how to put the belt in. Would anyone here have any idea on how to help?
