Hey Randy, I don't know if any of these questions were already answered,
but if not, here's my take on things.
Gruv Glide is crap. Don't use it. It leaves residue. Residue is bad.
Residue causes "a fair amount of gunk build up" on your cartridge.
Residue INCREASES friction. The best way of reducing friction is a
meticulous record cleaning regimen. If you can't afford a record
cleaning machine, at least have a carbon fiber brush around. They'll
get the big nasty stuff off the record. "The Disk Doctor" has a very
effective cleaning system that you can use without a record cleaning
machine. I'm spoiled with my VPI 16.5. It's so easy to use. I'd
advise you against using "home brew" solutions with tap water and dish
washing liquid. Both the tap water and the dish washing soap will leave
residue on the vinyl and may make the problem worse. Matter of fact,
some of the residue left by tap water and dish detergent is more
difficult to get off the record than the goo you're trying to
eradicate. I hate to admit it, but I use pure anhydrous isopropynol to
clean LPs (which will destroy 78s by the way). It leaves virtually zero
residue, dries quickly, and it doesn't seem to hurt my VPI record
cleaner. There are residues from the record manufacturing process that
cannot be removed by soap and water. In chemistry, you learn of
different kinds of bonds: ionic, anionic, etc... You need a cleaning
solution that has some kind of solvent (alcohol, or Vertrel or???) to
get the really tough stuff off.
Actually read this site: http://discdoc.com/ I know that Duane Goldman
is on this list and he knows much more about this stuff than I do. He
also will disagree with my use of anhydrous isopropynol, but I like it
and it's convenient for me.
To clean your cartridge tip of general dust/debris, try using an
artist's paint brush (as opposed to the kind for painting walls).
They're gentle and get the job done. You'll have to cut it down to size
(or at least I have to) so it's easy to get under the cartridge. I
don't like the idea of using any kind of fabric. Suppose you get the
stylus snagged in the fabric and you pull the cantilever too hard? Not
good. The toothbrush bristles is a better idea. I used to use
denatured alcohol to clean the stylus, BUT, alcohol attacks the rubber
in the suspension of the cartridge. There is, or at least I'm told
there is, a special alcohol that can clean the stylus tip without
damaging the rubber. Audio Technica, supposedly, uses it in their
cleaning formula. Is there a chemist here that knows what I'm talking
about? Never make swirling/circle or poking motions with your cleaning
apparatus! If you want to poke, get a stick and look for a dog to
aggravate. Only pull from the back of the cartridge forward, just like
it tracks a record. If you push from the front of the cartridge to the
back, you are putting stresses on the cantilever and suspension that the
cartridge wasn't designed to take. Now days, I just brush it off. I
never clean it with any liquid that might "wick" up into the
suspension. There are (for the OCD audiophile types) ultrasonic
cleaners. I've never tried one. The thing to remember is that the
stylus is pretty tough since it's made of diamond. The thing to watch
out for is bending the cantilever or knocking the suspension out of whack.
The headshell issue: go to MCM electronics online and search for their
generic headshell. They're well made and cheap. It's a skeletal (low
mass) design. By the way, if you don't have a cartridge balance, like
the low cost Shure, you need to get one (from The Disk Doctor).
Adjusting the VTF without one is kind of risky. You might set the
tracking way to high, which might sound okay, but eventually the
cartridge will fail. I do tweak the tracking force by ear, but only
after starting off at the factory recommended setting with my cartridge
balance (always on the high side of the recommendation sounds best to
me). What you do by adding a heavier counterweight is change the
resonance frequency of the arm/cartridge combination. When you add a
heavier counterweight, you increase the total mass, lowering the
resonance frequency of the arm and cartridge combination. That's not
necessarily a good OR bad thing. It's just something to know. If you
are using a lowish compliance "DJ" stylus, the extra weight will fix a
common problem with DJ cartridges: mid bass bloat (a resonance that
occurs in the range of the music, causing the bass to be bloated and
thick). Very high compliance cartridges like the Shure V15 might have
problems with the extra mass added with the heavier counterweight. It
might cause "woofer pumping" where the suspension of the cartridge
cannot control the motion of the arm effectively (think of it as putting
economy car shock absorbers on a 18 wheeler--the truck is too heavy for
the shocks to be able to control the motion of the truck and the truck
flies all over the road). With very low compliance cartridges (almost
always a moving coil), the extra mass is needed to get the cartridge to
function properly. I've heard very good moving coil cartridges sound
bright and harsh because they were mounted on a low mass tonearm.
Hope this helps a little.
