JVC tt-101 repair


Got a JVC QL-10 with a 120V TT-101. Speed is wonky. Sometimes plays fine, sometimes spins a 1000 RPM, somtimes runs forward & then backward. Could use some help.

I’m looking for some motor hall sensors ..... they’re those little 4 foot parts that look like bugs.....I only need a couple and then my problems will be over after 5 years.
Help me.

@jpjones3318 Italy needs help 
 
The cost of repair and calibration is about $1000
In Germany it’s about 1000 euro + tax
There is a repair guru in Australia as well


You have to read this thread first if you’re looking for cheaper options (in USA or in UK). Many of us have TT-101, i have two of them, find symptoms in this thread, it’s all there:

In which country do you live? 
@lewm some people simply charge per hour for the tt-101 repair work, others just stated $1k estimate (but they already know it's not simple). 
Bill does not fixed Lew’s turntable, you’d better contact Dave Brown if you’re in US. His rates are simply $25/hour and that includes time for packing and shipping. He has fixed tt-101 and tt-81, find his contacts on hus website: modularsynthesis.com

But our jpjones should be the best option to fix and calibrate tt-101 
@gary7 if you are lazy to read the thread full of info about TT-101 repair simply email to Dave Brown via his site, he's the one who can fix not only synthesizers , but a TT-101 and he already fixed some of them for audiogon members. 
Did you resoldered all the eyelets by your own? 
This is what Dave adviced me to do too, but i never tried yet.

Anyway you have to run your turntable for some time to check it out. 
Great, i have two of them here, nobody touched them yet, but one of them is working only if i touch the platter by fingers first. The problem with the repair services is that some of them prefers the original condition, not after someone else repair.

After watching SoundSmith video i realized he could repair vintage electronics too. Maybe i should ask about their quotes and experience with TT-101. I'm thinking to send him one of my Victor direct-coupled MC cartridges for repair. 
Congrats, nice tonearm
Upgraded mine to UA-7082 (long version) with sub weight. 

I’ve been using 3 Victor UA-7045 in the past with MM cartridges like Grace F-14, Victor X-1II, Audio-Technica AT20SLa, AT-ML170 and AT-ML180 mainly.

I think it’s time to try UA-7082, now i have even additional sub weight for heavier vintage MC carts (Victor MC-1 for example). This arm has slightly higher effective mass, but i don’t care. When i checked this arm with Sony XL-50 MM cartridge on Sony Headshell i was blown away by the quality. So the UA-7082 has replaced not only my UA-7045, but also Luxman TA-1 lightweight arm. Another reason is just desing of the long arms which i like a lot (and i have room for it on my PD-444 turntable, so why not? :).

I will always recommend Victor 7045/7082 tonearms for its amazing value and absolutely top quality, superb engineering. Practically they are great too! 7082 is more expensive.
You can replace the bubber part in that tube, but i've never tried to do it myself, my arm is fine. Anyway all information can be found online. Some people replaced the rubber washer and it wasn't complicated.   

The easiest way is just to copy an url of a piture uploaded to facebook (or anywhere) by chosing this option with a right knob of your mouse, and post that link here.

Same with my both Luxman PD-444 turntables, there is no immediate stop like on Technics. Also the torque is not so high on start. But this is just another concept of the DD turntables. It has nothing to do with the fidelity or speed stability. Technics is just a monster of torque.

Donor parts available for everyone if you know what you're looking for. I don't think there is a shop of parts for TT-101. You can transplant a part from donor turntable.
