Vintage DD turntables. Are we living dangerously?

QL8 you're referring to?

Sorry if you're referring to that, he was dead, left some time for sale and then sold these days.

haaaah ok  ok..........  I thought the TT 81 was this sold on ebay

http://www.ebay.com/itm/JVC-Model-QL-8-TT-81-Turntable-/152408974834?hash=item237c4865f2:g:f~IAAOSw4...

I read in the TT101 service manual that it do not need maintenance and engine lubrication but I believe little.

All turntables and those who have many many years of life need cleaning pin and lubrication with oil and perhaps thrust pad as for Technics SP 10 MK
None of you have ever done this to her TT 101?

As soon as I finish restoring a pair of 10-SP II I will pass to the restoration of a TT101 does not work, is completely broken and given to me for free.

So I’ll have to completely take it apart piece by piece and I can see and understand what the state is spindle and thrust pad.

You will need a major revision to electronics, I hope they are not IC failures.

HI,
Mouser, RS components or Ebay......there are a lot of online retailers!

You can search the Panasonic series FC 85 ° range or rather the 105 ° range.
From what I’ve found, Panasonic produces capacitors of all values, alternatively Nichicon, Sanyo, Elna .... but you have to check if these brands offer a large catalog of choice from the manufacturer you will choose.

Unfortunately the present capacitors will be much smaller in size than those on the turntable; in 40 years technology has made giant steps for miniaturization.
You will need to adapt them.

Cheers

Shane-rather than buying the Denon....I'd be more tempted to buy his TT-101 as a backup to mine. Knowing how thoroughly and beautifully re-built his Victor is...I suspect it may be the best TT-101 in existence...?🤗

You write this because you have concrete evidence to believe is the best, or are mere assumptions?

it is a Epa 102 mk2 very rare but limited only to TP4 cartridges.

In substance it has the articulation EPA 100 with the arm similar to the series 501

@jp
very interesting the brochure, on the internet I had never found anything about it.


@downunder 
the arm collects the best EPA 100 and 500 but I believe it is limited to a narrow range of cartridges.
The TP4 cartridges have never reached the great quality and musicality of the traditional MM and MC cartridges and it is for this reason that it is limiting in choice, that you have supplied is a very good cartridge but
your turntable deserves the best for the cartridges.

ohh yes yes ..the P100 C mk4 is a great cartridge I know this very well, even your stylus or stylus and cantilever VDH, but you possessed a large cartridges park as many fans have this would be very frustrating not being able to play with everything.

For the dust cover I think there are screws in the hinges to adjust the inclination, try to see if I'm right.

@ Chakster beautilfullll your front-end wow wow wowwwwwwww

This is my SP 10 II restored from a few months but two more SP 10 II and a Jvc TT 101 are waiting for my job for this year.
Unfortunately I do not have the time to upload photos but I can only insert the link where I published my long restoration work.

Ma ce casso scriveiso vualtris, seso duicj rincojoniis?

Hi,

can anyone tell me if the TT81 engine and support is exactly the same as the TT-101 engine?

Would it be possible to replace one another?

@lewm 

I could only find the engine of a TT-81 but I do not want to throw money to the wind if I do not have the real certainty that it is compatible!

Are you saying that you may replace the motor of a TT 101 with that from a TT81?

Yeeees.... but only  if it were exactly the same!

then 2 similar but incompatible engines for easy organ transplantation.......

(*See the movie, "Young Frankenstein".)

ha ha haaa    lol   :)

@pbnaudio Thank you for your offer, we could write in private but I'm not able to make the most of this forum I can try to search in some way your mail :)

@pbnaudio inbox send :)

It would be interesting to open a specific thread for the plinths, initially this thread was born for the Victor TT-101 and similar turntables with so much electronics inside.

@pbnaudio
I do not know what to say, I expect to have some rest to take over the TT101 that I was given a few months ago, because almost nothing works and the engine spins fast .....display not work and it needs a great deal of restoration from me.
I hope to solve the many problems that he has

@pbnaudio @Lewn

I do not know grand master JP but, I’m sure, I can not and I do not want to send the turntable to the world; I live in Italy and would have an exorbitant cost of shipping, repairing, customs and taxes; I have to fix it and restore it completely and I have to do it yourself.
I’ve already got the service manual and I have a look at the two big mother board .... there will be a lot of work for me next winter and I hope there are no custom made ICs for this turntable.

I already have a decent experience with the Techncs SP 10 II ..... I have restored a pair with their power supplies by disassembling all screw on the screw (even the engine) I had to repair broken tachometer coil wires, and put everything completely new and two others are under construction.

All this is just for passion and because I love collecting old high-level turntables that would end up in trash because they're broken. :)



for example this is 3ad my last restoration with more photos If you are curious.......

@lewm 
Same answer for you  :)

@pbnaudio 

ooopss ....I forgot ..... for plinth there are many great looking photos on the internet and you tube for the TT 101 and others will arrive, but before the turntable will have to work, otherwise it's all worth having a nice plinth and broken turntable.  :(

@lewm 
@pbnaudio 

Many many thanks for your precious help..... I will keep in mind if insurmountable problems arise when I begin work.

Surely the turntable will need a complete recap first of all because the capacitors are all original (many failures happen because of the skills out of tolerance) and later I will be able to discover the remaining faults.

I hope everything is resolved without major problems (I'm optimistic) luckily in the world there are good technicians very competent for repairs and to give some advice on this turntable; In the states there is Mr.JP in Italy someone might find, in UK I found there is a good laboratory with plenty of experience on the JVC turntable also for our TT-101 (I need to find the address).

This does not rule out that if I need an unsolvable failure I will ask all these competent people to understand and solve the problem.

I hope so much is not broken some IC unproblematic but I understand that Lewm has some spare for sale.

My English is bad and writing is not perfect, so you can understand that I'm a stranger. :)

@lewm all right .......knowing if it will serve I will know it in several months I will keep all you up to date on development, I hope it is not necessary but thanks for your generous offer. :)

@jpjones .....many thanks for your suggestion :)

maybe everything can be...... but I do not know.

It would be sufficient to compare the TT 81 and TT 71 service manuals for example, but I'm not sure these models adopt the bi-directional servo.

Very interesting ... it is useful to look for some cheap model for spare parts.
A detail I do not understand about DDs is how the TT101 and the lower models use lightweight lightweight plates unlike the Technics SP or Kenwood L07D or other big turntables of the time.

In Italy no GT 2000 has ever been imported nor even the older brothers.
Great pity.

bad bad problem :(

@lewn

Such a subtle problem may indicate some cold welding, but it is too long to rework all the welds.

@chakster 
Some time ago I read of a specialized Jvc turntables dealer and a good repairer of all Jvc turntables, the lab is located in U.K.

Could it be close to you if I can find the address?

@lewnEverything can be ... I have no feedback from this old authorized delaer / repairer and I have not even read of any TT101 defective owner who, desperately turned to him; But asking if he is able to repair does not cost anything.

@chakster
No news for now. I just polished the platter to have it as new eliminating bad signs
I’ve seen the Russian videos on youtube a while ago ... it does not explain how it has been able to adjust it to perfection.

totem395
yes is sample version....Look if you can see the finish

n.p.  ;)

touchè      lol  :)

However, the good news is that you too can purchase the chip from Hong

Kong.  I think the part number is "SC3042A",

good notice

@lohanimal   What does "plonk" mean?

I found the turntable repairer that in the past had saved the link ..... I do not know how it works and what experiences it has, but if anyone in the future needs it can remember it.

https://www.wilkinsons.tv/?page_id=1173

Keep us informed if there are any news ;)

Parrotbee - will you sell the wreckage ?

good idea!! lol

@Chakster Sorry what is your country?

@lohanimal 
Read my posts a bit higher for the Wilkinson lab    lol

heeee he he heeee .....good transport 

@lewn egual for me

@chakster  
How did the repair workshop make a budget estimate without even having the turntable on the operating table?
Could you publicize the asking price?

@halcro 

are u this?

Best groove
I was referring to the time line laser at a 3.7 m radius

Unfortunately for me is a completely new novelty I do not know.  :(

Technics claimed the SP-10MKIII would maintain speed with up to one thousand tonearms tracking at 2 grams each.

Sure, look at this photo from the 1976 Japan Audio Fair during the presentation of the Technics SP 10 mk2 what it could do without speed variations; The MK3 is even an even more powerful engine.


http://i949.photobucket.com/albums/ad331/marika-johnson/AA.jpg



@Halcro     ok  ;)

The standard strobe on the turntable is not widely enough to control deviations?  

WOW........
The laser point is generated by the clamp?

Hallo,
interesting discussion .... I also we do here because for some time I got hold of a turntable JVC TT-101.

My model is a sample version..... It does not seem to brushed aluminum and anodized but left natural finish, serial number 10100575
Mystery?

Wow big turntables Technics  mk3 and also mk2.

I finished these days to restructure my Mk2 working about 18 months but only in limited time ....... but I'm happy because everything is back exactly like new.After a while I will also restore the TT-101 and aesthetically and electronically have big problems and is not perfect.

Hi Lewm

yes .... I was referring to your wonderful MK 3 but also the mk 2 ihmo is a excellent player.
