I have a denon DP-7F direct table (1989)ust wondering about the point of the arm the head of the cartridge housing is very close to the record any way to get that adjusted higher?


If the tonearm balance and tracking force for your cartridge are adjusted correctly, ignore it.

Eeeww, page 8 says the counterweight snaps on and the tracking force is factory set. Any self-repecting turntable should have precise manual balance and tracking adjustments. Or your counterweight is not on? Either way, I'd look seriously at getting the stylus checked for excessive wear if it's tracking too heavily. The manual says 500 hours of normal use. You'll be carving up your recordings.

Maybe post the question to the guys at Vinylengine

Record keeps skipping arm won't move toward center of record


Sounds like your arm is tracking too light. To proper set the tracking weight on most units you need to zero the arms balance so that it is balanced just at the surface of the record. Once that is done using the weight on the back of the tone arm, or whatever system your unit uses, there should be an adjustment by turning the weight on the arm or perhaps a lever near it. You owners manual should really explain all this and give the recommended tracking weight in grams and fractions of grams. Each weight is different for different styli. Take a look at your operation manual and adjust the weight. Let me know how you make out.

My brandnew Songwriter is not playing records properly. When a quarter is placed on the tone arm, it plays fine. Is there an adjustment I can make??? Marilyn

I didn't see the tone arm balance adjustment in the user manual, however that is what needs to be done. At the rear of item #39, on page 10, is there a dial with numbers from 0 to 4 or 5? If so, set the dial to "0" to see if the tone arm will "balance" (like a see saw) If not, the dial assembly (which is a weight) needs to be slid either forward or backwards to achieve balance. After balancing, turn the dial to a number higher than 0 to increase tracking force..keep increasing the tracking force until it stops skipping, but no more than necessairy. To much force causes wear/damage to albums. If there is no tracking force adjustment on the tone arm, I would suggest contacting Crosley @ http://www.crosleyradio.com/Support.aspx
Hope this helps.

Sears Tape deck/Turn table skipping!


Hi the pennies will mess up the stylus. There should be an anti skate setting at the back of the turn table, a round adjustable bit with numbers, increase the anti skate and then use the balance weigth (weight right at the back of the arm that turns to get the weight right. Set the anti skate with the tone arm light, then increase the weight a bit. Hope that helps

Technics 1210 tone arm Problem


This table should have an "anti-skate" adjustment. This is out of adjustment and putting to much tension on the arm. This adjustment is designed to insure that the needle tracks in the middle of the groove rather than one side. If the arm is out of balance and this os out of adjustment, the symptom you describe will occur. Hope this helps, Dan

Skid problem.


My first guess would be the weights as well, try and make sure you are adjusting them correctly. I have not seen worn needles skip that bad but some tracking problems can occur. The loss of SQ can be interpreted as the weights being off balance, so as the needle gets further away the sound quality and intensity decreases. That combined with your severe tracking problem makes me believe your weights are off. You should still check into the needles- for two reasons (make sure the tables are on a stable and level surface as well).
1- The needles may not be the right ones (DJ's often switch them around to get different performance)
2.If the needles are subjected to a lot of tracking problems they will wear quickly-Good luck

When i backspin the arm is forcing itself off the vinyl


IMO the problem can be solved in 2 ways, either move the counterweight on the back of the arm towards the turning point of the arm ( by just adjusting it 10 - 20 % of an whole spin you can adjust a lot), or buy an other needle which is heavier then this one...

I balanced my tonearms correctly. i think .. but the stylus jumps off the record and when i back spin (cue) the needle skates drasticly. can you walk me through the balancing proceedure and tell me how to...


Balancing the tone arm is a two step process. Set the needle weight adjustment to zero(0) and make sure that the tone arm is balanced. It should rest horizontally without touching anything. Next, set the needle weight (usually 1.5 grams). Both adjustments should be on the rear of the tone arm. That should cause the tone arm to drop toward the record and have the correct pressure for the needle. Also, check the anti-skate adjustment. If that is off, the behavior you describe will occur as well.

Re:


Hi Vat,
Although I live in Canada now, I was born in the former
Czecholsovakia. While I spent a year in the Czech Republic in
2006, I was amazed how advanced their technology was, in
comparison to Canada or the US. If you want modern technology,
Prague is the place to go. Anyway ...

1) As I said before, do NOT adjust the tone-arm weight up
and down. This setting must be set to match the stylus and
the cartridge !!! The wrong setting is very bad.

To get the weight adjusted correctly, do the following.

a) Check the cartridge and stylus (needle) specifications, on
the WEB if necessary.

A typical tracking weight is between 0.9 grams to 1.5 grams,
but this very much depends on the needle geometry. To much
weight will damage the needle and the record, but

so will too little, because the needle will not stay on the
surface, skipping or mistracking on loud passages.

Note that the tracking acceleration is proportional to the
the square root of the loudness, multiplied by the frequency
squared. So if the tracking force is too low, the needle will
bounce over high frequencies and damage the record as
well as the needle's tip.

2) Once you know the correct force for your needle, adjust
the rear weight for ZERO force, such that the needle just
floats weightlessly in the air. If your turn-table has an anti-
skating adjustment, set that to zero as well.

3) At this point the tone-arm should be totally weightless,
and should neither touch the plater nor swing up/down
by itself. It should float halfway.

4) A this point, adjust the rear weight's dial (not the weight) to
read zero. Note that the dial will slide, while you hold the
weight still. You have now calibrated the tone-arm's zero
point.

5) Now, adjust the weight (with the dial) to read the desired
tracking force, for example 1.25 grams.

6) Now adjust the anti-skating dial to the same number as
the rear weight. This setting compensates for the radial
(towards the center) component of the friction vector,
caused by the needle riding on the record groove, at some
specific (average) tone-arm angle.

7) Your tone arm is now balanced, and you should not
touch it after this, accept for minor adjustments.

For brand new records, you may lighten the tone-arm
by 10%. For old records, you can make it a little heavier.
Similarly, you can adjust the anti-skating to prevent a
record from skipping, but a bad record should be played
only once (and stored on your computer).

8) For some tone-arms and cartridges, the cartridge pitch
(up/down angle) is also adjustable. This requires a special
jig or gauge, supplied by the cartridge manufacturer.

The pitch can be adjusted either by the use of screws or
wedges, and by lowering / raising the rear gimble. On my
Technics SL 1200, the gimble elevation is adjustable with
a large ring, and my SURE V15 cartridge came with a guage
for adjusting it correctly.

9) It may also be possible to adjust the cartridge's yaw and
radius, but all of these adjustments should only be done
using the correct gauges and by strictly following the
cartridge installation manual.

10) NONE of these adjustments should effect the tone-arm
cueing or return process. There should be plenty of
clearence if the cueing mechanism is working properly,
except, perhaps, for the gimble elevation, if the cartridge
is unusually tall.

11) Is the cuing mechanism (i.e. the tone-arm lifter)
mechanical or hydraulic ?

Is it the lift consistent or does the tone-arm drop down
with time?

Does the tone-arm move parallel to the plater, or does the
stylus height change with tone-arm position (yaw)

You are looking for a mechanical defect in the cuing
mechanism.

12) How much over all lift do you get between the down position
and the up position? This should be at least 8 to 15mm

If the cuing mechanism is worn out, it may not move enough.

If it starts too low, it may move enough but not raise the
needle enough to clear the record.

If the cartridge is tracking too low, you may have to
remove some wedges or spacers between the cartridge
and the head, or lift the rear gimble if it is adjustable, or
get a different tone-arm head, that matches the cartridge
profile.

Finally as silly as this sounds, make sure that the
platter is fully dropped and properly engaged. If the
plater is too high, for what ever reason, this would also
cause the needle to drag.

Also make sure that the rubber mat on the plater is the
right one and that it is not too thick.

Hi, sounds more like tje stylus tip is gone and therefore the needle isn't holding to the grooves rather than a tracking weight or anti skate problem. Styluscity@gmail.com
