Complete Belt Kit for Sony TC-K35

all right so i have a sony tcw 301 dual cassette deck that a customer brought into me wanted to have it checked out but i have a small problem it has the sony proprietary system control cable there's no audio inputs or outputs on this whatsoever so it gets its power from the main unit with this ribbon cable assembly it looks like there's five pins so there's probably power ground left ground right possibly and then a second one i don't know which one's record and which one's play but let's go ahead and take it apart and see what's inside and maybe it just needs a set of belts or something so yeah here's one of the decks and if i just turn the flywheel look at that belt how loose it is on there so i'm going to say that's going to be a major problem because that belt shouldn't be that loose let's take a look at the other deck probably in the same scenario same situation oh yeah very bad s
