Unknown Turntable belt size - how to determine?

[William R. Walsh]

Hello all...

I recently dug up an old JC Penney MCS 2230 integrated stereo, and I'd like
to get the turntable going again. (Despite the source, it's a pretty nice
stereo system...the radio tuner works well, it seems to have about a 40Wx2
output power rating (which seems reasonable, having looked at the
internals), the cassette deck is a partial logic design with the ability to
skip ahead 1, 2 or 3 songs and the turntable itself is a linear tracking
type.)

Anyway, before I stored it, the turntable was in need of a new belt. I set
the belt aside and now it seems to be gone. I could have sworn that I read
about how to determine an unknown belt size in the FAQ, but I could not find
it just now. As best I remember, a string was used and placed around all the
components driven by the belt, after which a measurement was taken.

I like using fine wire for that sort of thing. Strings stretch. :<

Of course, you will want to think about the number you get from
such a measurement. E.g., the actual belt size may be smaller
than you measure to allow for a snug fit (?)

Does 24.5mm sound right?

A turntable belt has a lot of stretch to it.

You could do a Google search and find the belt like I did..............

OK,then after that,WHERE do you buy a new belt?
the store where I used to buy them locally has gone away. :-(

String. I've used it on many turntables where the belt turned to mush.
Technics tt et al were one of my responsibilities at the warranty repair
center before the CD made them obsolete as far as new home audio system
sales were concerned. One other thing is the width of the belt is crucial
in many cases. That determines how the belt sometimes rides the motor
pulley and can cause problems including dismounting of the belt and speed
inconsistencies.

Depends on the individual TT. I've seen belts made of rubberized fabric
that didn't stretch at all. My old Rek-O-Kut TT had a belt that would not
stretcch at all made of some woven vulcanized rubber stuff. Any TT with a
heavy platter like the Rek-O is likely to have a stiff belt. Some of the
el-cheepo tables with aluminum platter will likely have a more stretchy
belt but it's not etched in stone.

Well, I'm lucky to live near Berkeley (yeah, *that* Berkeley), which
still has an old-time electronics store (Al Lasher's Electronics). Been
there since the 1940s, and they have all kinds of belts for turntables,
cassettes and VCRs.

I can't remember the name of the line of belts, but I could ask next
time I go there.

Instead of string, which does stretch, you might try a strip of paper.

Which reminds me of an old turntable I used to have. As a kid in Tucson,
not quite 20, I found a used turntable in a junk shop there. Cheap,
because it had no belt. Took it home, and being the resourceful lad I
was, I made a belt out of paper, the ends glued together with white
glue. Worked great! No problems with wow & flutter or rumble. The paper
belts lasted maybe a month or so before breaking. The bulb-shaped motor
pulley kept the belt tracking true.

Can't remember the brand, but it was an interesting turntable. Very
simple: just a deck, a motor, a spindle with inner and outer platters,
and an arm mounted on some kind of isolator. The arm had a single pivot.
Worked really well. (My poor man's AR.)

The whole idea is isolation. All mine had loose belts. My
best Thorens TD-125 was stretchy. Had a SME arm to install on it, but
sold them both.

Loose and stretchy are different things. The belt on the Rek-O was loose
too and I agree that isolation from the drive is a good idea. A stretchy
belt, with more stretch than what is designed, is not good for speed
stability or drift.

I'd like to know if they make good anti-tank weapons. Knowing they are the
bane of the life of drott and dozer drivers operating on council landfill

of tights and stockings fired into tank caterpillar drives would do the
same.

Not even on 'Casual Fridays' in the US military. OTOH, they did sell
men's pantyhose with a fly at the PX at the US Army cold weather
research center and at least at Fort Wainwright (which is near
Fairbanks) if not at every cold weather base. They were available in
either cotton or nylon. They were very heavy material, and made to wear
under your thermal underwear to prevent its seams from wearing through
your skin. They were also sold to mailmen to wear with their uniform
shorts. This was in the early '70s and they were expensive. It doesn't
take long to decide between wearing them or getting frostbite when it is
below -40 most of the winter.

Hi!

Does 24.5mm sound right?

Well, it seems very, very close.

http://www.turntablebasics.com/belts/penney.html

This one seemed to have a somewhat broken system, as the page said
that the belt was in stock. Yet when I tried to order one, I was told
that the belt was out of stock. Okay, whatever. Maybe that site needs
a little nap?

http://www.vintage-electronics.cc/ (snipped)

This one seemed to work OK, and was a few dollars cheaper.

I usually deal with Studio Sound Electronics, as they were mentioned
in the FAQ as a source for these kinds of parts, and I've been happy
with everything I ever got from them. As long as I met the minimum
order (so as not to get charged a few bucks extra), everything was
fine. (They don't carry a 24.5mm belt.)

It looks like I'm going to have to replace the tape deck belts.
Everything was OK until I tested the recording mode and then the
cassette belt fell off. It's totally flabby and spent. This doesn't
look like fun to me.

I was surprised by the uniform dust carpet (!!) inside the unit, given
that there are only vents on the back. I was also surprised to see a
hybrid audio power amplifier module (STK4151 II) as opposed to a
discrete power amplification setup.

Hi!

Does 24.5mm sound right?

Well, it seems very, very close.

http://www.turntablebasics.com/belts/penney.html

This one seemed to have a somewhat broken system, as the page said
that the belt was in stock. Yet when I tried to order one, I was told
that the belt was out of stock. Okay, whatever. Maybe that site needs
a little nap?

This one seemed to work OK, and was a few dollars cheaper.

I usually deal with Studio Sound Electronics, as they were mentioned
in the FAQ as a source for these kinds of parts, and I've been happy
with everything I ever got from them. As long as I met the minimum
order (so as not to get charged a few bucks extra), everything was
fine. (They don't carry a 24.5mm belt.)

It looks like I'm going to have to replace the tape deck belts.
Everything was OK until I tested the recording mode and then the
cassette belt fell off. It's totally flabby and spent. This doesn't
look like fun to me.

I was surprised by the uniform dust carpet (!!) inside the unit, given
that there are only vents on the back. I was also surprised to see a
hybrid audio power amplifier module (STK4151 II) as opposed to a
discrete power amplification setup.

near enough 1 inch wide or 1 inch ring diameter ? surely not 1 inch diameter
of the rubber cord . Or 24.5 cm ?

Seems that it's 24.5 *cm*. I wasn't paying any attention to the unit
of measurement and probably just corrected it in my mind without
thinking about it.

If you still cannot find one.
Try making your own , details on my tips files below.
Find a scooter/motor bike inner tube right sort of diameter , cut a strip,
cut across the width to make thinner . Maybe cut from a flat sheet of .5 or
1mm rubber. The set in the "cylinder" probably no matter for a record deck,
smaller one for cassette deck requires offsetting angle of the ballister
pulley drive.
