Best way to replace belts on an acquired Onkyo TA2700. Nice deck, great specs but belts melted which I understand is common when stored. Thanks for any help. I have purchased the belts but can't seem to replace the internal larger belt.

It can be a bad capstan belt, bad motor or a power supply issue. I would have to see the unit to tell you what. I replaced motors in Onkyo TA2700 units not too long ago. The little DC motors in them do not last forever. But the units can be repaired in the right hands.

. Remove top lid (4 screws on the side) 2. remove the back plastic mount on the mechanics (2 pink long screws on the top). The bottom are two plastic hook lock. The mount pulls back and the belt and pulleys are exposed. NOTE: It is the mount you are removing, not the tape deck itself.
By the fault you describe this sounds very much like a belt problem. Take the case off the deck and check the belt(s). Some decks can use more than one belt and you need to look at their condition.
Are they too slack around pulleys maybe? Belts don't last forever and I'm not too sure of the age of your deck. But personally, I would change them all.
Make sure the tape path is clean as well, clean heads, pinch roller and capstan.
Understand your idea, however, after 35 years of repairing mowers, most manufacturers have designed drive sheave pulleys to certain specs, and generic fractional horsepower belts do NOT work. The material, cord design, and cross-section measurements are specific to that particualr application. Fractional horsepower belts are normally just rubber, and the heat created by driving a mower will melt the rubber quickly.
Go to the local Cub dealer and get the proper belt. It will save you tons of time and money. If you do not have a local dealer, cub has a website that would provide a dealer locator for your area.
The Onkyo CD changer has an internal mechanical problem that could be anything from a disc being jammed in the mech, to a bad belt, or a bad IC or supply voltage that goes to the servo circuit. No way to be certain without troubleshooting it. You can open it up and see if a disc is stuck, but unless you have some experience in this sort of thing it is better left to a professional, You can cause more damage than you started with by trying to fix something you don't know that much about.
The tape deck could have any number of problems as well. A bad belt or gear, a defective servo circuit, and the list could go on, but they are all things that also should be checked by a professional. Most of the time a tape won't eject is form the tape head being engaged and not letting loose of the tape. But since it won't turn off, you have some more serious problems. That is an indication of something not communicating with the microprocessor. It could be a digital transistor, a shorted capacitor, and like before, many other things. Whatever you do, don't force the tape deck open. It will destroy the head assembly and it may even void your warranty (you did say it was new). You need to find an authorized Onkyo service center near you. Contact Onkyo if you can not find one yourself. This really is the best action you could take. Onkyo is a very good brand, and in most cases is worth getting repaired. If it were some type of cheap-o brand it wouldn't matter what you did to it because replacing it would always be cheaper than paying for a repair. That is not the case with your equipment.
