Yamaha GT-750 Turntable Repair, Service and Clean

[@warrensharpe5630]

Great video...appreciated...A beautiful Yamaha turntable...with a little love and care and these Japanese turntables are built to last...I have a P-350, a P-20 and a P-220...very reliable and serviceable...

[@mrtim6]

Thank you for the excellent video. I have had two Yamaha turntables in this series- GT-2000 (now sold) and GT-2000X build quality superb. Great turntables

[@TheStuffMade]

Thanks, yeah the GT-2000 and the GT-2000X are certainly a few steps above. This GT-750 is more like a budget version of the top models, but it's imo still a great turntable that also looks great. Most people don't realize how large they are.

[@sung-minpark9789]

This is really really helpful to me, thanks a lot!

[@Inconceivable-Montoya]

Great video guide thanks. Considering buying one of these

[@TheStuffMade]

Thanks, it's a great turntable, I've been very happy with mine, just keep in mind it's very large, almost twice the size of a regular turntable. Cheers, Jake

[@Inconceivable-Montoya]

I like its size, mass adds to a certain amount of stability to the sound IMO. The model I am considering has no original headshell, I am thinking of Yamamoto to replace it. Thanks again, you really helped me know what to check out with this TT@@TheStuffMade

[@TheStuffMade]

@@Inconceivable-Montoya Absolutely the large platter, direct drive motor and heavy/solid plinth contributes to it's excellent performance, far better than most modern high-end turntables. Also worth noting that Yamaha used the same arm in their top, very expensive, high end GT-2000 turntable. The original headshell does have azimuth adjustment (as in you can twist the head to the perfect angle) but I have a lot of different cartridges on different headshells and I've found it not to be an issue, you can still twist them a tiny bit while securing them to the arm and achieve prefect azimuth. Cheers, Jake

[@Inconceivable-Montoya]

one more question, when you serviced the electronics did you leave the platter on as the table was on its side? did it leak any oil from the bearing housing? thanks @@TheStuffMade

[@TheStuffMade]

Service and minor repair of my Yamaha GT-750 Turntable. This model was only sold in Japan and never exported, however it became very famous in Japan as a high end turntable with excellent performance.

TheStuffMade thank you for some amazing content, if you dont mind me asking, where are you from? :-)

[@schmidt8744]

Great job!!!

[@TheStuffMade]

Thank you! Cheers!

[@undress62]

Great video. I’m amazed!! I’ve read that adjusting tonearm bearings is a very difficult and delicate thing. That the ones that know how to do it uses special devices to ensure proper really tight tolerances. Also read recommendations to change the whole tonearm if you have a loose bearing. So this is the first time I’ve seen anyone doing it and I’m amazed that you did it so tranquil. It’s really that easy? Is your tonearm 100% perfect now and tonearm makers exaggerate their claims?

[@TheStuffMade]

Thanks, for this type of bearing I'm confident it will perform just as well as new after the adjustment as there is no damage, most important is to make sure the tonearm is centered and the bearings are not too tight, only just tight enough there is minimal slack. It's typical for Japanese turntables of this era to use low friction ball bearings, Yamaha, Technics, Sony etc. However there are many types of tonearm bearings like sapphire, ruby, magnetic etc, they all have different challenges some require special tools, but mostly because the manufacturer designed it that way, some of the most annoying ones are the nuts that are round but have two tiny holes in them. Cheers, Jake

[@MrAlmat-mh9di]

Thank you for your review. In the same way, I eliminated the backlash in the tonearm. There was no damage. I twisted the bolts carefully. However, after eliminating the backlash in the tonearm, the downforce settings for the needle were lost. The error in the indicators is visible on the electronic scale. How did you deal with this problem?

[@TheStuffMade]

Hi, it will not affect the downforce when done correctly. It sounds like you might have made it too tight, it should be just tight enough that there is no slack, but no tighter than that, it can be difficult to do. When you tighten the outer lock screws make sure the center screw doesn't move at all, it might take a few tries of loosen and tighten until it's perfect. Also make sure you have the tonearm perfectly centered and it's not rubbing on one side. Cheers, Jake

[@MrAlmat-mh9di]

@@TheStuffMade Thank you very much for your advice. Today I will experiment again. It should all work out. Good luck to you.

[@Bess216]

Hello, my gt 750 running at 33.31, how to adjust it to 33.33? is it a rezistor on board that turning with screw driver? And it has wow 0.12, its not good for this motor, i should replace all capacitors?

[@TheStuffMade]

Hello, this turntable uses a crystal oscillator to control the speed, it's not adjustable. I wouldn't worry at 33.31 RPM it's only 0.06% off and could just as easily be the measuring method as the turntable being off. I assume you used your phone to measure wow? I did an experiments with 4 different phones some time ago, they all gave very different results, so it could just be your phones accelerometer not being suitable for wow measurements, also for best result make sure you use a box or perhaps a large roll of packing tape so the phone is centered on the platter, if your phone isn't centered the off balance weight will affect the result. Try a different phone or try your phone on a different turntable. The wow could also be caused if the cast aluminum got cracks in it, it's worth removing the platter to inspect or if you notice the plater being uneven when it's spinning. Besides that I'd inspect the capacitors for bulging and leakage, if they look ok I'd leave them as is. Cheers, Jake

@@TheStuffMade thank you for answer)

[@dimis094]

I hope the oil has no detergents or other substances regular engine oil has ( to prevent corrosion, etc. )

[@TheStuffMade]

Sure, I generally don't buy oil with additives. It's usually specified on the label. Although most oil, additives or not, would still be better than 35 year old oil that has acidified and oxidized. Cheers, Jake

[@TheWretchedWorld]

Mine was the same. Looked as though it hardly got used.

[@TheStuffMade]

Yeah, I think many of these turntables were only used for a few years then replaced with CD players, they probably spent the last 30+ years collecting dust while in storage.

[@ceejaydeesoozaa]

i guess this offers much more value than spending much more on the gt2000?

[@TheStuffMade]

Considering they use the same arm, I'd say you get 99% of the performance for 25% of the money. Cheers, Jake
