Question about Audio Players & Recorders
Stuck on high speed
Posted by Anonymous on
This is because the unit has hard dried up grease in it and needs to be taken apart and cleaned out and new Lubriplate 105 grease applied as that has never been known to dry out at least not in the 40 years I have been working on these. These old Sony unit usually require 3-5 hours to get them working again. Better off buying a restored Teac A2300S, SX or SD.

There is a surprising interest in "vintage" hifi products these days. Your tape machines probably needs new belts. Check this site out. You can get spares for your tape machine here. Belt kits are $17. He does repairs also, but the transport to and from may be an issue for you. I suggest emailing Bob, he may be able to refer you to someone in CA > I could do the repairs,but I am in Australia. :)

SOURCE: Sony reel to reel TC -765
I too had this problem with my tc765. I found the two pinch rollers were not lifting up and fully pushing the tape against the rotating capstans in the play/record mode. Solution to my problem involved partly dismantling the pinch roller assembly, cleaning off the old solidified grease and re-lubing with a molybdenum grease. Note: the top plate has to come off first,then the rotating guides and tensioning pegs. Then the cast head cover and flap. It was a time consuming operation, but well within the scope of competent DIY in my opinion.

MOst tape drive problems of this nature can be directly attributed to failing belts and idler drive surfaces. If you are a bit of a mechanical gun, you could overhaul and resolve this problem yourself. You can get a belt kit to freshen up the deck from here
Replacing them may be a little daunting if you are not mechanically minded, but within the realms of most home DIYers. Happy to help you with advice and answer any questions you may have if you choose to go this way. Cheers

Testimonial: "Thank you for your very kind help. I shall try replacing the belts first. Kind Regards, wilf"
Sounds to me like your Sony has a common problem among vintage reel tape decks..dried /frozen grease/ and or a lack of lubrication. carefully apply a tiny bit of fine lube oil, like 3in1, on the swing mechanism that carries the pinch roller...(you may have to remove the front metal deck face to fully access the swinging pinch roller mechanism) ) . do NOT get any oil on the rubber pinch roller..(best to make sure after by scrubbing the pinch roller surface with a cotton swab lightly dipped in non chemical household cleaner, like 409, or awesome orange i get at the dollar store. Then use the dry end of the swab to ensure the pinch roller is dry. .The pressure pads should swing upward and press the tape against the heads when in play/record mode..if they do not swing up, they are binding/ or out of adjustment....they are spring loaded so when the reel deck is in the stop position the spring loaded pressure pads are held down...play/record mode releases them to freely swing up and press on the tape against the heads.
