Question about Audio Shelf Systems

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.

    OK, Just a tip, put a small coin at head of stylus to maintain its wight on record.

The turntable belt wasn't atached and i need th know how to put it back on.


Good day. Lift the rubber mat off the platter and notice the two rather large holes in the plater. Put your thumb and forefinger through the holes and pull the platter off the turntable unit. Place the platter upside down and notice the inner rim which holds the belt. Place the new belt around the inner rim and replace the platter onto the unit. Now, with tweesers, working through one of the large holes, pull the belt onto the spindle motor. Once on, spin the platter by hand and make sure the belt does not slip off. Hope this helps

MAKE MY TONEARM STOP SKATING


It's possible your weight adjustment has been mis-adjusted since you last used your turntable. On the tonearm, there should be a weight adjustment wheel. Turn this all the way towards the needle (IN). Now, adjust it backwards until there is no resistance in the tone arm - this is your zero point, reset the wheel on the weight adjustment knob to read 0. Now, adjust it forward to 3 grams of downward pressure. This is usually the minimum amount of force needed on a record. If it still skates at this setting, adjust it with gradual amounts of greater force until the skating stops.

Hi, I have a technics stereo system from 1986.


If the turntable is belt driven you may have a stretched and slipping belt that needs replacement. This seems most likely and is simple to fix. You will have to lift off the turntable to see the mechanism beneath. It may be held on by a nut or clamp. A web search for the model name and "dirve belt" may yield a replacement.

If it is driven directly by a motor without a belt, the motor is probably dying. Replacement more involved, expensive, and hard to justify, unless you're really into vinyl.

Troubleshoot auxiliary equipment


There is no Phono input on your JVC.

What TT are you trying to hook up? If it's a traditional one you would need a preamplifier to boost the tiny signal from the cartridge to a suitable level for the AUX to use.

If you have an old traditional receiver with a Phono section hanging around you could rig something up between it and your JVC.

Plug the TT into Phono on the old receiver. Run RCA cables from any Tape REC output to the AUX. Done.

How to replace belt in jvc turntable


I just got a JVC turntable from a thrift shop today and as soon as I got it home the belt broke. I had a replacement but couldn't figure out how to install it. After taking off the back, which is about 4 screws plus the 4 feet and the grounding screw, I saw a very tiny set screw on the post where the spindle obviously is. I removed this and the table came right off so I could replace the belt. I couldn't get the tiny set screw back but figured I didn't need it and if I ever have to replace another belt, I won't have to take the back off anyway. I hope this helps.

JVC turntable--broken motor?


I just worked on a unit with the same problem. The spindle bearing will seize up if it is not oiled at least once a year. Take off the feet and split the top and bottom. Remove the three screws that hold on the spindle. Remove the E clip that holds on the gear. Put it in a vise and press off the gear and remove the shaft. Thoroghly clean off the shaft and the bearing. Lub with 3 in 1 oil and reassemble.
