Question about Audio Players & Recorders

10 Answers

I am getting in touch with my inner-vinyl and pulled out my old JVC AL-A95BK turntable purchased in the 80s which I have not used in at least a decade. I tried to play a record and the arm skates across the record horribly. I thought it might be the stylus perhaps being damaged so I ordered a brand new one for $30 and just replaced it but the arm still skates across the record. I cannot see how the tonearm weight/tension, etc can be adjusted. It says it is a "Tracing Hold System Tonearm" and it has "Adjusted Anti-Skating". What am I doing wrong?

    The owner's manual is very brief and was helpful for changing the stylus and adjusting height of tonearm but mentions nothing about adjusting weight or anti-skating.

  • bartatl Feb 24, 2009

    I do not have a manual that is helpful in any way with this tonearm/skating problem.

  • bartatl Feb 24, 2009

    Everything at the end of the arm is static. I see no way to adjust or turn a knob as with turntables I've seen in past.

  • bartatl Feb 24, 2009

    I'm sorry but I cannot find anything at the end of tonearm or at the base that can be adjusted, turned, or moved in any way. There is a plastic section that says "adjusted anti-skating" with numbers on it with an arrow set to 2.5 but it is only printed on plastic. It is as if the turntable comes "pre-adjusted" with no way of adjusting it. Is that possible?

  • bartatl Feb 24, 2009

    Thanks but I was trying to avoid spending more money. Could it be that a "statically balanced tonearm" means just that...that one cannot adjust it? I'm really beginning to think this particular turntable/tonearm system does not allow anti-skating adjustment since I see NO way to do it and the option is not mentioned in owner's manual.

    OK, I will look into replacing the coil assembly. I assume this is something that can be found online and replaced by opening the bottom portion of the turntable. Thank you!

If you stick a penny on the tonearm, you will dig into the grooves of the record. If it says static adjusted 2.5, it's pre set at the factory for 2.5 grams of tracking pressure. Make sure the needle (stylus) is either in the anvil or in the groove where it mounts properly. Out of at least 1000 of the repairs I.ve done, no less than 600 were related to the stylud not being installed correctly or the wrong replacement stylus was used. Modern parts houses don't have a lot of experience with turntables and they will sell you something that looks right but 1/10 millimeter in the diameter of the needle holding feather (Part of the stylus) will be like trying to put a Cadillac engine on a MoPed.

Tracing Hold System Tonearm is moved by mechanics with springs anf hidraulic pistons, when it skates that way the system is bad and some part must be replaced.

This is a job for a specialist.

Dear bartatl,

RE: 80s' TURNTABLE "Tried to Play a Record and the Arm Skates Across the Record Horribly"

I actually remember having the same problem with my vinyl record player back in the 80s'. I can't remember the players name but I do remember it was like I had ejected the vinyl record on the turntable but instead of the arm lifting up and dropping the record above the play arm went nuts on the record on the turntable.
I think I loaded a bunch of records and hit the reject lever then grabbed the arm and yanked it.
I can't remember if this worked or not but sometimes I just get the urge to use my favorite tool "PERSUASION" so I believe I grabbed the arm and pulled it to where it should have been going. If that didn't work, I'm sure I PERSUADED it into little pieces for parts and got another one fast because......
I had some great vinyl music records and I do remember playingthem on a great,n even older (1959s' "Stereo" Portable) that someone had thrown out!
You gotta love the "crack, snapple, pop!"
Enjoy!

Have you got into your vinyl side enough to look at the same level as the spinning record to see if it is warped ?

Hi there, i have recently had this same problem as well. To my surprise, i found it to be the coil assembly that was malfunctioning. i simply ordered a new coil assembly and it was all i needed. no more skating. I later replaced the entire tone arm assembly as well. it works like a charm.

Hi!

Use a blank record or a record whose lead-in grooves are fairly widely spaced. For a start, set the anti-skate to the same number as the tracking force the cartridge is tracking with (i.e. set it to between '1' and '2' if the cartridge is tracking at 1.5 grams). With the turntable running, lower the stylus onto the disc the same as if you were going to play it.

Best adjustment is when the arm will slightly tend to move toward the center of the record--almost stationary. If the arm tends to slide off the edge of the record the anti-skating force is set too high.
There's a dial by the base of the tone arm that controls the anti-skate (no, not the big one that controls the tone-arm height, although that could also be a problem) that needs to be set to the right value for the cartridge you're using.

Please ask for further clarifications.

Thanks
Rylee

    Check to make sure that the TONE ARM LEVER is completely DOWN. You can also check for tone arm balancing by setting the tone arm weight to zero.

    Then see if its perfectly balanced (the tone arm is leveled and completely parallel to the turntable, do this without a vinyl on the turntable) by tightning the screw.



    Then mark this as zero on the weight measurer. Now put vinyl on the turntable and slowly turn the weight to the specified weight for the needle. If not know use somewhere between 2.5 or 3.

    Have you tried smooth surface test?



    Also try altering the bearing(s). Modfification can take place with the screw on the side of the tonearm where it meets the pivot.



    Anti-skate feature on your turntable is simply the friction of the lateral bearing assembly (shaft in tube) and was designed for substantially heavier-tracking cartridges than we use today.



    If you are still unable to adjust it then i would suggest you to replace the whole tone arm assembly as that is the only way to fix the issue.

You need to adjust tonearm balance so stylus needle can stay in record grooves.

Check any weight adjustment at end of stylus arm.

Turntable arm not moving across record?


Try, without any record on the table, if you can move the are, to the centre of the table. If you feel anything that is holding the arm, try to find out what it could be. Never use force. Also look inside if you can't find a clear obstruction on the top of the table. If you should find anything, don't bent, or don't break anything. Let a technical skilled person look why the obstruction is there and where the "thing" should be so the aren can move free. Perhaps you ned the obstruction for something only a few centimetres to the left or the right.

I have a JVC turntable (AL-A155TN/AL-A155TNX). I haven't used it in about ten years. I hooked it up today. I played four records on it. Two were fine. The other two, however, started off fine


The only thing that might cause something like that is a build up of static. You can buy anti-static products for records and turntables. I tend to use an anti-static spray which also cleans the records.

JVC auto return turntABLE - mODEL al-a95bk


when you said "no sound enough to enjoy listening" did you mean that you could hear something coming thru the speakers, but it isn't loud enough? if so, you may be plugging the turntable into a "ceramic" phono input on your stereo. it may be that your stereo doesn't have a pre-amplifier on the phono inputs. Ceramic tonearm cartridges (the part that holds the stylus - which you may call the needle) have enough output level to drive an amplifier. if your cartridge is magnetic, the output is very low compared o the ceramic. the trade off is that magnetic cartridges have a much wider dynamic range than the ceramic, and when properly pre-amplified, sound MUCH better than a ceramic unit. you can probably find a separate pre-amp at radio shack (i know they sold them several years ago). you plug the turntable into the inputs of the pre-amp, then plug the pre-amps output into your stereo. hope this helps.

When record has finished playing, the arm keeps running in the inner groove. No lift and return to base. What's wrong? The outfit is quite old, but none of the new gadgets I've purchased can match this...


I am glad to find a real Audiophile and I fully agree with you for the quality that analogue tracks give out.
The arms mechanism needs a resetting as when the arms comes to the end there is a link to detect and make the arms to be lifted up and brought back like a clock work. so there is an issue here which needs attention - mechanically. You need to look inside the unit, manually turn and find the fault.

I just had my L-A11 in to 'the needle doctor' (Jerry Raskin's shop in dinkytown, Minneapolis) We had the same problem with the platter.
After pulling (hard) to no effect on the platter - using the holes near the spindle and pushing simultaneously on the spindle. The tech next got out a small hammer, and while pulling on those same holes in the platter, he gave it a sharp 'whack' on the spindle with the hammer, and it came right off (the platter). I would have been to feint of heart to do it, but it worked great.

More than likely your motor might be bad. There is nothing else that controls the speed. Are you sure you purchased the correct size belt? Turn on the unit, without connecting the belt, and touch the motor shaft, and see if it fluctuates. You can also just get a marker, and marker a point on the motor shaft. When you turn it on, it will act as a visual indication as to it's speed.
