for refurbishing a tape deck, I need some belts. I googled a few places but
nothing very inspiring (not a great selection).
Anybody have a source they like and use?
(If you're just going to Google, don't bother, I've already done
that...)
Thanks!

Russell Industries bought out the old Projector-Recorder Belt Corp several years ago and still carries the "PRB Line":

They should have your belts. Just give them a call.

But do they say whether they are new belts or old stock (so half
perished already)?
The total absence of any supplier stating they had new belts made me
move over to cutting my own belts , flat and square , from silicone
rubber kitchen products, no returns yet from broken examples.

I have had excellent luck making belts myself from fresh O-ring stock. Or, from O-ring suppliers. Where a 'weld' does not matter, from stock. Where it does, from a supplier. They come in about every size (circumference) and diameter from a millimeter or two to 20+mm in circumference, and diameters from 10mm to over a meter. And in enough materials to cover about any need.
One of many, many: http://www.oringsusa.com/
My local plumbing supply house has not let me down yet as far as that is concerned. Not also that O-rings often do a fine job even where flat belts may be OEM. If there is any sort of lip on the wheels, there is rarely a problem. Note that diameter does not matter where belts are concerned as long as the tension is sufficient for traction. The pulley sizes are all that matters. And new materials often have a much higher tension strength than OEM belts typically of neoprene or even basic buna rubber. So, thinner O-rings may be used ILO flat belts if clearances are critical. And, as we all know, buna-rubber is not good around electrical stuff...

I've always wondered about the freshness factor of their stuff these days.
They must be selling dozens of belts a month these days.

If I ran a company supplying rubber drive belts, I'd make great play in
my blurb, that they are new cut/moulded stock.
As none of the companies I've found selling belts for legacy equipment
say this, I assume they only have old stock , next to useless stock.

The problem is balustre/bulbous pulleys which must have flat belts.
If its possible to cant over the motor and pulley, it is possible to cut
belts from smooth flat rubber sheet and offset the set by the degree of
cant to the pulley axis.
I often use Orings for pulley tyres, often using 3,2 to take up the
width and one centred on those 2 to make the depth to bridge the gap to
capstan drum or whatever.
There will always be sources of O-rings because they are used in all
sorts of areas. Anyone know of other uses for the very thin flat drive
bands <>0.5mm thick, other than old tape recorders and projectors?
Vacuum cleaner bands are for power transfer and always too thick ,even
sliced in half , retaining one fair face to go against the drive pulley.
Some old style photocopiers used to use thin <>0.5mm and <>20mm wide
rubber bands for paper conveyance, easily sliced down in width, but I
only ever saw one size of perimeter

There are dozens of sources for miniature drive belts, ribbed, notched and flat. There are many hobby applications (I use them for drive belts on a miniature R/C submarine I am building (a 5-year project)). But consider robotics and any of several other applications, hobby and commercial.

Are only a very few.
I find it interesting that those who are "in the trade" tend to think within the trade and not outside it. A lesson I learned from a former colleague that struck home came to me as follows:

Look up "back-up" rings - they will be flat on the OD, and concave on the ID (and may also be turned inside-out). And pretty much ideal for shaped pulleys, whether concave or convex. Some care will need to be exercised on choosing the material, however, as these beasts range from spongy-soft to PTFE (quite hard). Nitrile is probably the best option for small electronics applications. Again, the range of sizes available is quite astounding.
