I'm restoring an old four track cassette Teac 144 at the moment.
The pinch roller, idlers etc have certainly seen better days. They are
not melted or falling apart.
I've seen this 'Rubber Renue' product recommended, but it seems to only
be sold in the US, and nowhere I can find will ship internationally.
(Mouser, MG Chemicals will not. RS and Maplin don't stock it.)

Does anyone know if there somewhere that sells it over here, or an
equivalent?

Replace them all.

If it's what I think it is, it's methyl acetate, and it works well on
some kinds of rubber to soften them. There is another popular product
called "Fedron" which was a chlorinated hydrocarbon, which worked well
on neoprenes and natural rubber.

The problem is that there are hundreds of things called "rubber" which
are all chemically different.

Replace the pinch roller and idlers, and expect to replace them again
in another five years. None of the rubber softening agents will really
do what you want. The parts should not be expensive. Russell Industries
in the US should stock them if you don't want to buy from Tascam.

I have not held much hope of getting replacement parts, so have not yet
called Tascam. It's worth a try. Those generic replacements from Russell
Industries should be fine though.

The pinch roller might be a bit more tricky. I found a place (http://
www.terrysrubberrollers.com/) that rebuilds them. A little excessive for
a four track cassette perhaps. He says he finds soap and water to be
roughly as good as rubber restorer in the long term.

Tascam is actually very good about parts for older equipment. They still
are making new pinch rollers for the Model 38.

There are a lot of places that do rebuilds, but it's not worth it for
something like this because if Tascam doesn't have a replacement, Russell
will. Russell has several pages of different pinch wheels for cassette
decks in production.

Thanks again. I'll get in touch with Tascam and examine that site more
closely.

If by "that site" you mean the TASCAM web site, you won't find much
encouragement about parts. Send them e-mail, or better yet, spring for a
phone call. TASCAM isn't as independent as it used to be and basically
all their parts support comes from TEAC. If TEAC has a service facility
closer to where you are than California, try that first. Even though
TEAC didn't put their brand name on your deck, they built it, probably
from parts that are used in several other transports. They almost
certainly have a "common parts" list and can sell you a new pinch roller.
