This Technics SL-1350 had a misadjusted set down point and needed some
damping fluid. The arm now has a slow and smooth descent but the anti-skate
force is pulling it outward as the arm is slowly lowered. I've cleaned the
arm lifter but the tonearm occasionally still will pull to the right as the
arm drops. Sometimes, it misses the lead in groove and record completely.
Since the customer likes to stack his records for convenience sake, the lift
arm height cannot be lowered too much. The tonearm lift is no longer
available, part number SFPRT13003K. Anyone have a fix for this?

Thanks for your reply.

I'm confused.

While the arm is being lowered, it should be in contact (somewhere, above-
or below-deck) with the lifting mechanism, right? Should there not be
sufficient friction between the arm and the lifter to keep the anti-skating
force from moving the arm?

Yes, that is the crux of the problem. The rubber portion of the arm lifter
which contacts the tone arm seems to have lost its grip. There isn't enough
frictional force to counteract the anti-skating force.

A thin piece of rubber such as from a balloon maybe, superglued to the
underside of the tonearm above the lifter ?? A very slight 'dent' filed into
the lifter perhaps ??

Sometimes a rubber item can be rejuvenated with ... brake fluid.
The stuff in your auto brake lines is intended to keep the rubber
seals all flexible. A few cotton swabs and a few drops of brake
fluid
might be useful. Give it a few hours to 'soak in' then re-apply.
It's a glycerine-based product, wipes up with a damp cloth.

There are also rubber rejuvenators, but that might be too much trouble for
this particular problem.

We used to use a product called Fedron to rejuvenate the lift rubber.

Seconded. It works well.

It's a delicate instrument... I'd suggest hitting it with a big hammer.

BTW records are dead, get with the times and buy some CDs and DVDs or should
I say blu rays.

Idiot. They are still releasing new LPs and pressing them. They are
still manufacturing turntables, as well.

Not so. Records are still big business and much sought after, and decent
phono decks sell for staggering amounts of money ...

And since he seems not to have noticed, CD sales are in the toilet. And
the new hot release format seems to be LP + download.

Try to find a R-R tape recorder, or even a cart machine in a radio
station these days. OTOH, some still play 78s and Transcription disks
from the '30s & '40s. Spots, tags, jingles and commercials are stored
on a hard drive these days, but you still find turntables in studios.
WSM in Nashville is on station that plays old records.

BTW, 'The Grand Ole Opry' will return to the Opry House on the 27th.
It was badly damaged in the flood earlier this year. They haven't said
anything about when their studios will be moved back from the tower
site.

I tried a liquid called Rubber Renue. It seems to have corrected the problem
for now.

Such precise troubleshooting methods are reserved for things that just
don't want to be fixed.

What a troll! Are there even blu-ray audio discs being made?

Absolutely. Both 2L and Naxos have issued them. The appeal is the
availability of extremely high fidelity multi-channel sound, in a format
less-likely to be abandoned than SACD. The 2L recordings, in particular,
have exceptionally high-quality sound.

It would seem to me that if the anti-skate is pulling the tonearm outward,
before it even hits the record, then its set WAY to high.

I do not think SACD is going away any time soon, i can master them on my
home linux box. It is not missing from the MSWin world either.

Your ability to master SACDs has nothing to do with the music industry.

We don't know how long SACD will last. Some audiophiles consider it the
best-possible currently available sound, but its multi-channel capability is
not only of no interest, but anathema to a large percentage of audiophiles
who claim to want good sound quality, but persistently reject the industry's
attempts to provide it. In a world where too many listeners consider
phonograph records the height of sound quality, there are no guarantees.

Harmonia-Mundi has almost completely stopped new SACD releases (even of what
are probably multi-ch masters), and is not re-pressing older ones. (This is
not altogether surprising. By not adopting a single-inventory system, H-M
effectively shot itself in the foot.)

Other companies, such as BIS, PentaTone, and several orchestra labels, have
been successful with SACD.
