Surely, but Europe is also far from the U.S.A. yet there are Europeans who ship cartridges or turntables to the States for upgrading or refurbishing them.

Hopefully the documentation, brochures leaflets and like are downloaded to AK's
specific document repository Digital Doc's.
Makes tracking down 5 years from now a logical place to start.
BTW I get the impression AK's Digital Doc's repository is under utilized by members
and the unregistered visitors?

For some reason I cannot get the motor to come out of the housing. I can pull it out a bit, but it has a lot of resistance when trying to completely remove…like something is holding it back. Any suggestions?I think you need to take the engine (it's not complicated) apart and check the pivot and oil if there is still any.

you simply have to detach the multi-wire connector from the pcb and unscrew 3 screws, it's very simple.

I've only had two JVC tables here, the QL-F4 and the JL-A20. I looked over their tables while I had these and it looked like they made a pile of models using the design of these. Only the F4 was DD and Locked. The A20 a belt drive.
Adequate starter table the A20 but I was impressed by the improved feel of the control levers after oiling the pivot shaft.
The F4:
Interesting thing about both tables, it seems most of the weight was in the heavy metal bottom plate.
Both have been moved on and hopefully a college buddies son got the QL. I wanted him to get that one and I think I finished it in time to get it to him for Christmas one year. He's the bass player for REZN and has a few very limited production albums out. About 500 copies each.

looks good in your photos. It responded well to the lubrication, too.

Bill, been reading this thread since the gig. JVC sure did make a pile of pretty nice looking tables and arms. Now that you have raised the awareness/price of these machines gonna be harder to add one to the play list to see what is up but at least I know to look at them. With a bit of study I'll even learn some of the hierarchy, features and benefits of certain models.
Technics seemed to make battleship gray models sort of blend in and not noticed. Kenwood was all over the map with the ARCB white tables, dark gray, ebony, and wood looking units. But Denon and JVC made tables that really had a look to them.
This thread dang near needs "Official" as part of the title.

I think you got this a bit off. If in fact the additional platter mat was pigskin, then the winner would be JP for the mention. but wouldn't the fact the mat is pigskin make the pigs the losers?

Excellent that these two posts are adjacent and you got the table working again so quickly. But it would be great to know the problem and the solution for those that might have the same issue in the future, unless it was just that the table was unplugged.

For the platter cover, it was two skin pigs with a turntable crystal in between. Skin was chosen for its really low diameter.
it was a system chosen by Victor after several tests, I forgot to upload its files.
Victor 70s belts are cheap versions of their 60s models often, even if some rare models of 10kg are actually quite equivalent to their old style.
Direct drive models were excellent actually. They have been quite famous but as time goes on, they'll value more not only because of recognition. But because also of new turntable asked prices with an industrial design.
Victor ones looks classic, with rosewood and such. However, please think to consolidate the plinth.

Are the arms the same between QL5 and 7? I was finding 5045 and 7045 models as standalone arms but the “oem” arms on the 5 and 7 both look like the 5045.
I was considering a QL-5 that was posted for sale locally, but looks like someone else bought it. I am going through the thread a bit to get more familiar with the JVC models to narrow down what to keep an eye out for as I don’t see them come up very often. I have several tables already but quartz lock in an attractive package for the prices the JVCs seem to go for is appealing. I don’t like auto functions and am only looking at the manual tables.

It is a main part of Victor history actually this turntable and is very rare, I have no idea if it still runs and if it does, if it is in 50hz and if belts are compatible with B40 turntables. 
It was the most expensive turntable of the 60s made in Japan (Micro Seiki luxuous models included with highest tonearm price as well), part of their major system they used in july 1966 for their experiment. The experiment was simple : around 1200 listeners in an auditorium were watching an orchestra playing live and around, was a Victor system with 12 speakers each of 77kg. The listeners were audiophiles, critics and musicians, so quite used to go to operas and concerts at this time and therefore, had a sharper ears than most moderns critics. They had a paper on which they had to say when the orchestra was faking music and when it was not, around 0.8% of the people got it right. Victor started those expeeriences in early 60s, first with a reel to reel system, then few years later with a record player. It was the final experiment they ever did of this kind due to all the company being involved at every level to make it happen and work smoothly.
The sound was so good that at the end of the piece, the musicians actually stopped playing and it was the system that was working on and people kept smiling. After few minutes of course, the public was starting to notice sound was made without any musicians playing their hands, and even critics of the time recognized they were "fooled" and appreciated it. Finally, the whole room cheered up and started to burst into applause, to the ease of the Victor staff who congralated themselves after those minutes of tension, awaiting for public reaction.
It is extremly rare, I have seen more TT-101 than this one and have a very strange feature : it have apparently a 2kg platter, and a 4-pole beefy motor while 8-poles motor were already available as well as heavier platters. I am really curious about it and about the tonearm as honnestly, Victor never went for highest prices except for this line so it's quite a big surprise to find it.
It does not mean it is on the same level of the TT-101 but I like to go into old history and I am really curious about the source of such event, especially that moderns belt drives are obsessed with platter weights.
The inside looks like this :
I already think to shield the transformer !

Ok so the srp-469 arrived. I'll do pics of the whole thing tomorrow because it was dirty and needed health care.
It looks strange actually, very classic and appealing. The plinth is nicely finished with a strong acrylic protection, that's the main reason for it, that and the design. However, it does deserve a much sturdier plinth, you can feel the 60s style of plinth in here.
The mechanisms and parts looks very nice, with some early automatism system, however the lower part of the axle can't be unscrewed, too tight. Will need a solution. As the result of that, a previous owned tried very hard to force on the platter achieving in bending the platter. It's a shame because it's really well finished! Will have to make it flatten once unscrewed. I think all parts are working otherwhise and I hope it's 50hz. It's a pleasant turntable, I am curious about the sound even if I am scared it looks better than it sounds due to its age and story.
The tonearm coming with it is really nice even if no informations to use it can be find as they all contradict themselves. The only sure thing I can tell about it is that its overhang is 5mm and according to placement on the turntable, it have 225 or so mm of distance to the spindle. And it have been mounted by Victor themselves over a metal frame (probably aluminium). Yet, a separately sold tonearm with a template seems to indicate another geometry.
I'll try to listen tomorrow to the tonearm, it came with an old IM cartridge from Victor but the stylus doesn't look so good. The headshell plus cartridge made 30g! It took me a while to clean the tonearm, remove some rust on the turntable and such so my apologies for tonight pictures that will be only about the tonearm.
I tried to used the lateral balance but I can't wrap my head around it and Victor made it easy to remove thanks to a big screw. Whatever I do with the balance, using all kinds of manuals asking to move higher the turntable back or such, the lateral balance always end up messing up with the VTF after. The positive side to remove it is that it allows my 21g mount headshell plus cartridge to be installed ( otherwhise 21g is too light!!) and if I need the 30g option, I seems to do a great job at being a secondary weight.
I also readed it was to prevent the tonearm to move left or right but tonearm is deadset on its location. It is currently over the Micro turntable as I would like to hear it till the srp-469 can start spinning otherwhise than in my dreams.
It looks very nice however. It have charm, I don't know why but it does despite the plinth being too thin. You can see actually early CL-Px serie pattern but to a fraction of it.
The tonearm looks cooler with the lateral (and looks complete too). It is a totally different design far from the later 7045/7082 style and their huge technological use to make it pretty and highly precisely cut.

Today for the pictures of the turntable and all assembled. I am taking care of the wood first, the turntable is pretty nice for 1966. They could have just make a simple turntable but no, they had to make it more refined.
I am gonna keep cleaning the turntable and will do internal pictures as well. Motor is pretty big and beefy as well and they made a kind of system Micro Seiki used later for their bl series.
Yes it is dynamically balanced, and it's very different from 7045 : the 7045 is pretty free to move. This one is not so much, yet the bearings as I assume there are at least two because it stays vertical seems to be huge.
It also needs to be redone : the back rubber is dead, is still holding and working but is covered with cracks. It also seems to have some internal dampering in the tonearm (two screws underneath it locks a kind of arm cueing side, I'll add more pics). Not sure a rewire would be in order but a refurbishing should be done. Not bad for an ancestor of the QL-Y line.
QL-Y line looks like sci-fi in compare and utterly modern!!!

Some pics of the turntable, it needs to have wood cleaned and fed before applying some oil.
The turntable in itself have the dead belt and pictures may not be the best with the hour. The spindle is still locked and some scratches shows attempts to unlock it. Also the platter is only unbalanced on one side which is strange.
I thought it was the platter but whenever I turn the platter, the the platter remains unbalanced on this side.
The tonearm is working and sounding yet it is a proper nightmare to set up. Catridges exchange and tries would prove to be torture with this model.

Some pictures of the plinth : the plinth is extraordinarily light. I'll try to weight all items one by one but I think the acrylic cover weight more than the plinth. It feels very light.
The turntable looks so good all together, it deserves a new platter with the same style but, heavier. Motor have lost two of its rubbers feet or never had them.
Also the unbalancing can be seen.

So after some more cleaning, the turntable works and look quite good and takes a huge space.The bearing oil is 75w90 or 85w90 and motor oil is 10w40. The axle is quite original for me as it have no bearing as pictures will show. I think it have been reworked one time hence the stuck grease on the axle that solidified and the fact that the bottom of the axle cup have a conical receiving shape while it have a polymer shim.
So far I noticed, the axle and platter aren't locked, like quite free, it remains straight while spinning but you can move the angle.
The speed isn't fully 33rpm, despite being quite close, I have see nothing to set up 50 or 60hz so maybe it does it automatically.
