I have an older QL-45 turntable that needs tone arm adjustment- I don`t know how to set the weight so it doesn`t lower down to album so hard or heavily

Adjust the weight on end of tone arm. It is not hard to do. when properly adjust the weight in stylus is 0 Adjust out to add weight.

Yes. you need to set the travel on your arm. I don't know your specific model but they are all the same concept. On the back by the pivot point there should be a small screw that you can adjust the travel before it returns.

I gather you don't know how to adjust the tonearm. First put the stylus pressure, and antiskating to zero. Balance the tonearm for a free floating position. Ortofon cartridges will list the stylus pressure, generally 1.5 grams. Dial in the correct pressure, and set the antiskating to the same as the stylus pressure. If you require more assistance, or would like to inquire about repairing your Technics, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

The service manual shows the adjustment for the tone arm set down position is accessed from the top of the unit. It is in front and to the right of the pivot point of the tone arm. The other problem is something that I can not diagnose here but I am providing a link to the service manual. You will have to set up a free account with vinyle engine. The service manual is a free download.

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.

Thanks for using FixYa

What is the weight on the stylus? Flip the protective shield down to protect the stylus if available. Tare the tone arm (adjust the counterweight on the back of the arm until the arm floats perfectly level), then hold the counterweight and turn the dial markings to read zero. If you cannot find the recommended mass for the stylus you can use the average weight of 3g. Verify your tone arm is still floating in the center and the arm is perfectly level. Turn the counterweight until the dial indicates the specified weight of the cartridge manufacture specification sheet or you can set it for 3g if you do not have the specification sheet.

HELLO

Make sure you have the deck set up correctly! Check the headshell - is the cartridge out of alignment or is the stylus worn?

Also, it may be that the counterweight is set too lightly for the cartridge and check the anti-skate control as well (example if the arm is tracking at 2 grams, anti-skate must be set at 2).

Follow these instructions for setting the counter balance:

Turn the weight so that the arm is just floating then set the balance ring (with the numbers on) you will see there is a line. Turn the ring not the weight to the ZERO mark where the line is on the top of the arm. Now turn the weight and ring together where it moves forward down the arm and set it at about 2 grams.

Now set the arm using the height adjustment that is the ring fitted to armboard and make sure the arm is straight (if not, the stylus will mistrack). Now try the deck again. You might have to make adjustments to the tracking weight again so whatever you have it set to, set the anti-skate to the same!

Good luck with it (:-)

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.

You need to adjust the downward force by adjusting the counter weight which is on the back of the tone arm. Rotate it so it's closer to the tone arm fulcrum to increase the weight on the arm, like tightening a nut on a bolt.

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.
