Sony TC-K80II Cassette Deck Repairs (Ep. 222) 

Superb work great looking and sounding deck.

CFL is a Compact Florescent Lamp and they last much longer than an incandescent with less heat and a better light color temperature for those devices and more even light distribution. 😊

For these small holes I cut small lints from thin cotton (hanky's are perfectly fine). Take it through dry first, and then put a drop of cleaning fluid. Pull through.

Sony really made some cool stuff back then. Good thing that none of the white gears was broken.

Use disposable makeup applicators for cleaning of small points where Q-tips won't reach.

Very nice deck, restored with care. Thanks for sharing.

I bet you wanted to keep that one boy,what a nice unit. You're probably running out of space with all the goodies you have. Nice video!

Lube the gear to gear interfaces as well.

Beutiful deck, great work. Thanks

Good production Trevor, small holes I cut-off cotton and the cardboard stem works pretty good for absorption. I can see that getting $1000.00 in 1980, does have outstanding lighting. You are correct, only 2 head. No glue for that cracked plastic wheel ? Nice seeing that Sanyo integrated, own that w/ FM Tuner.

Rubber Renew available on Amazon. Small and large sizes.

Cassette decks are so hard to work on, parts are so small and everything is packed in.

Please service the motors too. Won't be long until they have lube issues as well. 😁

COME ON PEOPLE GIVE THIS GUY MORE LIKES

I was never a fan of cassette players there were too many things to go wrong and there was an incredible mix of technologies from many different eras.

Keep in mind here, that workers had to hand draw every component you are removing since their wasn't any CAD programs yet.

Yes rubber renue is still available

I had to send my cassette deck from the Midwest, all the way to California, for repair.

Hello Trevor, I am following your channel quite some time - great motivation to my projects. I read from time to time that it is worth installing or replacing so-called audiophile transistors in the preamp circuit board, especially with old devices. Do you have any experience with this?

Trev, why not just use 99% iso and avoid the risk of the plastic segments melting or going brittle over time? You can still buy that poison Rubber Renew. I use it for idler tires on Dual TT. I find you need to clean the part the following day as it oozes out a film of oily rubber poo. If you soak am idler tire in it the rubber swells up like 30%. It returns to normal size in 24 hours. I only use it outside with gloves on. Not looking to grow another head from my neck. Dr. Cassette recommends using windex to clean rollers as it will not dry and crack the rubber rollers. Idk... just FYI.
