Technics SL-Q300 - Basic Servicing

One of the later Technics Quartz decks gets a service.

[@travisrysdam6725]

Thanks for doing these videos. Your first video of the Dual CS-515 gave me the courage to tear apart and fix a CS-620q that I happened upon. I've fixed up half a dozen turntables since then (gave away most, kept a couple). I've got a line on a SL-Q300 that I may pick up this weekend, and I feel pretty prepared for getting that one up and running.

One of the best affordable fully automatic direct drive tables ever made. I've bought and sold many of these.

[@len9518]

Had the same platter mat on my sl-Q303, It was hard as a rock. Bought a Fluance mat for $20, and cut out the openings. Most folks use alcohol to remove old grease.

[@garretts91]

That was a basic service. From my experience, the rest of the greased moving parts will gum up eventually, not a matter of when. If the customer was willing to pay it'd be beneficial to unscrew the entire moving assembly and remove all the old grease and replace with new synthetic grease.

the weight can be adjusted ,theres a screw in the back of the counter weight ,i have done it

[@TurntableGuy]

Good to know.

Hi, I got one from eBay and it works fine, but I couldn't fix the humm sound from the gound. Do I need to solder it from the inside? A s I'm using a Fosi audio Box X4 phono pre amp. Thanks

[@cassandraarnold7439]

Thanks!

[@davidwillard275]

Thanks for your video! I have the Technics SL-QX300. I am having issues with the tonearm dropping too quickly. I assume that damping fluid is added under the arm-lift adjustment screw (which I have done). The tonearm still drops rather rapidly. Is there another location is should be added? Any help appreciated.

[@TurntableGuy]

You probably need to disassemble the lift piston from the cylinder and re-coat the entire mechanism with silicone fluid. I have several videos showing the procedure on different tables.

[@kiwicory100]

LOL good video... I guess I wasn't I the only one that noticed you left the clamp in the unit when you put the back on....funny, anyway thanks for the advice on the lubrication for the spindle. I have the next model up and have a hum, waiting for the ground wire to connect to see if that fixes it. Ps since it has phono jacks and my receiver has a phono line in, I can go straight in, but I also got a preamp, wonder if there is any harm pushing the signal through the pre amp and then into the phono line in? Any thoughts?

[@broederbond60]

I saw that immediately.

[@stevewalther843]

Excellent service video. I just got my hands on an SL-Q300. The only issue it has is that the tone arm doesn't lift enough at the start or return at the end of play. It basically bumps into the edge of the record at start and scratches across it when retuning. I can see the lifter move VERY SLIGHTLY but no where near enough to lift the arm properly. I saw the mechanism moving when you had it apart but it seems fairly inaccessible. I'm pretty handy but is this something to leave to a professional? I'd love to get your two cents on this. Thanks again for the excellent content.

[@TurntableGuy]

There should be an adjustment screw on the lifter arm.

[@stevewalther843]

@@TurntableGuy Thank you for the reply. There is a screw built into the saddle (?) that raises to push the tone arm up from bellow and drops to lower it into position. The screw adjusts the overall height of this saddle. Is it just a a matter of finding a very fine middle position? The cue control doesn't really move the arm at all and the automation only moves it at most a millimeter at the stylus end. If I could just disable it and cue manually I would but the auto return scratching across the record is forcing my hand. I really appreciate your free advice and won't keep asking follow ups. Thanks again.

[@TurntableGuy]

@@stevewalther843 You need to open the bottom and see what's going on. Quite possibly some old grease preventing the mechanism from raising the piston that raises the arm.

[@geepee4804]

I think I have the same issue! Will check that out.

[@cemeloks]

I've used your video to help me service my deck. I'm having an issue where it starts to spin the record too fast for about 30 seconds then it slows down to 33 RPM. Any idea what the issue might be?

[@TurntableGuy]

It could be one of the controller ICs.

[@michaelkristofka3933]

Thanks for your Technics SL-Q300. My problem is that the Start/Stop button does not turn it on. The turntable does not spin but if I manually spin it I can get the needle to work but when I stop manually spinning it, it stops. Do you have a video on how to resolve my issue?

[@TurntableGuy]

Probably dried and hardened grease on the mechanism. Clean and re-lubricate.

[@michaelkristofka3933]

@@TurntableGuy Ok thanks. I don’t have a lot of confidence doing it myself. Think I’ll need to take it to a pro to fix. Unless you have another video by any chance that shows how to clean it and re-lubricate?

[@williammorley7667]

Use flex super glue. It works great for plastic parts.

[@jackiepoo6943]

Question for you: I have an SL-Q30 and it has an issue where it continues to spin faster and faster without stoping at 33 of 45 rpm. Any idea what the issue would be? It’s been in my family since it was brand new and I’d rly like to get it working again. Thanks!

[@TurntableGuy]

I'd guess one of the speed control ICs has died unfortunately .

[@jamesbruins444]

Is there a way to service the anti-skate? Mine just wants to slide across? Thx

[@TurntableGuy]

Your needle may be broken

[@qhoward3284]

Noob question when u say “I didn’t connect the ground” what do you connect the ground too I’m not sure just got one of these from the thrift store yesterday

[@TurntableGuy]

There should be a ground post on your amp/receiver. The ground wire from the turntable gets attached there.

[@alexxbaudwhyn7572]

11:00 2 part epoxy done deal. Ends up stronger than original joint and will break somewhere else in the future

[@jmax5105]

I have this same turntable and am looking for a replacement stylus. Do you have any that you would recommend? I'm not really even sure what to look for, but want something that will sound as good as, if not better than the original stylus that came with these. Thoughts?

[@TurntableGuy]

There are so few choices in a p-mount these days. Look at Audio Technica.

[@mariuswichern9081]

Little late but Audio Technica has the AT85EP, it's a pretty good pickup for P-Mounts

[@lukkkie]

I have this deck and it’s worked great so far, but now i have an issue were sound only comes from one speaker and if i pan it to the other speaker there is no sound, if i jiggle the stylus a bit the full sound comes on but after a while it starts going only on one channel again. I have another stylus and it makes the same problem… im thinking it could be the cables along the arm to the cartridge or some bad contact in it…

[@TurntableGuy]

Try a different headshell. Watch my video on diagnosing bad audio channels: kzbin.info/www/bejne/f3-ygZWtZdCkock

[@lukkkie]

@@TurntableGuy that video is fantastic! great job, im going to check it that way, i hope the cabling on the headshell is as simple as on the turntable you had on the video

[@Revortay]

Help. Everything works fine except the cartridge is sliding across the record after playing the first track. I thought it was a bad stylus so I replaced the cartridge and stylus with AudioTechnica. Same thing. I’ve had this turntable done new but it has been in storage for quite awhile.

[@TurntableGuy]

Check the arm weight and anti-skating first. Next check to see if the arm lifter is not touching the tonearm when the record is in play and the cueing is in the down position.

[@Revortay]

@@TurntableGuy I’ve tried resetting the arm weight and that doesn’t seem to do it. How do I change or set the anti-skating

[@Revortay]

@@TurntableGuy Never mind, seems that my Creedence Clearwater vinyl that I’ve had since 1969 might be a bit worn out. Hah.

[@paolomusella1006]

Hey Thanks for your video. If you still have the turbtable can I ask you a thing? I just get one of these but without the original mat with the holes. Can you give me the model number on the back of the mat? Thank you in Advance!

[@TurntableGuy]

I'm sorry, the table is no longer with me.

[@paolomusella1006]

@@TurntableGuy no problem, thank you anyway!

[@coby5806]

Great vid thanks, can I use the singer oil for the tone arm area where you wd 40 those spots?

[@TurntableGuy]

You need to clean off the old grease with either alcohol or WD-40. The oil won't clean the grease.

[@coby5806]

@@TurntableGuy alright, and then I can use the singer oil? I do t have that white oil you were using

[@coby5806]

@@TurntableGuy thanks!

[@TurntableGuy]

That was white lithium grease. Yes, Singer oil for the main spindle bearing.

@@TurntableGuy also my auto start stopped working, I don’t think I need to adjust the screw, it just stopped working

[@MrUran11]

Did You get a little clamp out?

[@TurntableGuy]

If you mean did I take the clamp off, yes.

[@MrUran11]

@@TurntableGuy You used a peg clamp to hold the glue bond, then on the video as You putted the bottom cover on, You left the peg clamp inside.

😀 i was like ... the clamp is still inside 😂😂
