Just inherited one of these with a Ortofon Concorde 20 cartridge. Everything still works and sounds great. Definitely saving this video incase i ever need to service it one day. Thank you!
I finally got the 3-in-One Motor Oil on a trip to the USA a few days ago and serviced my Realistic LAB-400 turntable. The direct-drive motor was almost dry, very little grease. I cleaned the bushing pit and axle and then re-lubricated with fresh oil. Very helpful your videos, thanks a lot. Greets from Mexico.

Not a bad deck (if a bit hollow and plasticky) but the main gripe I've always had with the QL line was the rubber decoupler on the back of the tone arm (what the counterweight threads onto) degrades with time causing it to sag.
Hey, very nice videos, mine have the speed no stable so 32 to 32.8 rpm in 33 and 40 to 40.6 in 45. I not understand everything on your repair. Did you think it's capacity ? Or it's the glue ? 👀
Thanks as always for your detailed videos. Very helpful! I'm curious what the charge was for servicing this turntable? I have one that may require a similar service. What city are you located?
Unless you live in Southwestern Ontario (London area) and can drop it off, I can't accept shipped-in turntables. A basic service such as above is about $50-60.
Another smaller accomplishment by jvc was the CD4 four channnel discrete audio, which could be considered the predecessor to Dolby digital multichannel audio on movies
I have one of these on my rack. It will not q-lock in 33RPM. This is a nice table. I have spent tens of hours working on it. Recapped every capacitor. Checked every diode. Dismantled the speed switch and cleaned it. Added a pull down resistor to the IC pins 11 to 14....JFC.....
Very nice video and the main issue you cleared was of the glue around the two caps.I gave JVC QL A5 TT.The platter rotates for just 5 minutes and then stops.The strobe light remains on.There is no variation in the soeed atv33 and 45 rpm,it is on target.There us glue around one regulator transistor and tge two main caps.Tge regulatir IC becomes too hot but it us with a heat sink. Could you please help me to get this sorted out.I am from India.The platter is so jammed that it is not coming out . Thank you for reading.
Love the video but surely any owners first port of call to a system that is not sounding right would be to the stylus, did they not clean it a dirty head like that will make a considerable difference to listening, I would be mortified to bring a player to be serviced and having a filthy stylus and saying to someone it just don’t sound right.
