JVC QL-?? owners thread

BillWojo said:
Had a little time yesterday so I finished up the tonearm insert for the Victor arm. Still need to get it all set up yet. I picked up a nice black granite piece of countertop and had it cut to the same size as the plinth. I'll set that on top of my 16" deep rack. TT is 20" deep so the feet would only be touching on the edges.
Unfortunately I'll be very busy this week with work so I probably won't get back to this until next week. But all the hardware is finished. As usual my pictures leave a lot to be desired.

Bill, you're table is coming together really nice! It's making me think about adding an arm to my QL-A7
Decosse, your table looks awesome! Love the wood veneer you choose.
Ibcgav, I would be crying if I had to give up that beautiful table!

@EThorn66 , picking up a QL-A7 is what put me on my quest for building a Victor based table. I was shocked at just how good that table really is. And great looking as well.

I agree, JVC made some high performance tables back in the day that can run circles (Haha) around pretty much anything.
 
Long time lurker, and a big vintage JVC turntable fan. I have both an L-A31 and a QL-Y5F, and both are great tables from the golden era. I have the QL-Y5F paired with an AT VM540ML cartridge, and it shocks me every time I play it at how good it is, even with less than stellar vinyl.

I saw there was some confusion in the earlier posts regarding the JVC numbering. Don't necessarily assume that a higher number or double digits is better in the JVC lineup. It's more a product of when the turntable was released. Here is the breakout from high to low by year for the US market using JVC's own available brochures:

1978: QL-10, QL-8, QL-A7, QL-7, QL-5, QL-F4, QL-A2, JL-F30, JL-A20
1980: QL-Y5F, QL-Y3F, L-F71, QL-F61, QL-A51, L-F41, L-A31, L-A21,
1982: QL-Y55F, QL-Y7, QL-Y3F, L-F71, QL-F61, QL-A51, L-F41, L-A31, L-A10
1984: QL-A75, QL-Y66F, QL-F320, QL-A220, L-F210, L-A120

As previously speculated, the Q models are Quartz Locked, L denotes coreless direct drive motor, Y denotes the Electro Dynamic Servo Tonearm, F denotes Full Auto operation, and A denotes either Auto Lift or Auto Return depending on the model.
 
Good to know my QL-Y7's rank second. This is a good informative deal you have here 'darkrider'

While not the "top" model, the QL-Y7 is one of the most desirable IMO. It was a tweener model as the technology was evolving, replacing the QL-Y5F. It used the same original ED Servo Tonearm as the QL-Y5F, but separated the controls from the tonearm base and made the tracking force independent from the anti-skating. It shared the higher torque motor of the QL-Y55F and has a larger/heavier 322mm/2kg platter and a heavier better reinforced plinth than the QL-Y5F. The QL-Y7 weighs 28.6 lbs, which is the 2nd heaviest of the 80's models, only bowing to the QL-A75 which has a bigger footprint. While not as complex as the tonearm on the QL-Y55F, 66F or 77F, the simpler design has fewer parts to fail, and shares the same performance specs as the QL-Y55F. I really like the fact that they kept the S-shaped tonearm with an H4 bayonet headshell mount. The interchangable tonearms on the Y55F and newer ED Servo tonearms are nice, but are increasingly difficult to find these days, and it makes cartridge changes more difficult/time consuming. Lastly, JVC kept the outside the lid controls similar to the QL-Y5F. From an ease of use player's perspective, I think the QL-Y7 may be JVC's best design!
 
Some more good info. Thanks for posting. I need a switch for the up/down mechanism, I cleaned it using deoxit and destroyed it. Problem is can't find any parts table for a Y-7

I don't think the L denotes coreless motor, it's really based on the model and year. For example, in your 1978 row, only the QL-10, QL-F4 and QL-A2 were coreless, whereas by 1982 their full line of DD tables used coreless motors.

I went back to the 1978 brochure, and it was a bit confusing since on the 2nd page it shows a "Core-Less DC Servomotor" as part of it's universal quartz technology, but you appear to be correct based on the spec summary page, as it only shows the QL-10, QL-F4 and QL-A2 as having this and the others list "DC servomotor". By 1980, it actually lists all of the direct drive models as having the "Coreless DC Servo motor". Here is a snapshot from the 1980 brochure where you can see it if you zoom in:ql-y5f brochure 2.jpg

Yea, most of the Japanese companies jumped on the coreless motor bandwagon pretty quickly, other than Technics and Denon. The first coreless motor direct drive table was out of Germany way back in 1973, the Dual CS 701, pretty amazing table for the time, one of the quietest direct drives ever built. Those EDS-1000 motors have quite a following still.

The QL-Y7 panel looks to be the same size/layout as the QL-Y5F panel, minus the LEDs. I wonder if you could pull the switch from a QL-Y5F panel and use it on your QL-Y7? There is one used on eBay right now, https://www.ebay.com/itm/JVC-Victor...324256?hash=item3b4dcc97a0:g:vRQAAOSwn9VfUMSA. It might be worth putting in an offer...

I looked for a switch for months and gave up and you found one in 5 minutes. I bought the assembly, thanks.

All it is is momentary, here is a photo. None of these worked for a week till I finally got them dry but the one on the end never did work again. I soldered in an alarm switch and it works fine but looks horrible. Learned a lesson on this one.
 
I used deoxit when I cleaned my switches as well, so I'm glad that none of them froze up. I'll definitely take it as a word of caution! Hopefully the new switch will work out for you. Definitely keep us posted!
 
Nice tables, I couldn't part with a QL-10 if I had one either. What cartridge are you using on it? Is that the UA-7082 tonearm? I've been looking for one for my build.

BillWojo
 
My tonearm is the UA-7045. The UA-7082 is a 12in arm. I have a 12in Jelco on my other TT a Denon DP-80. I would love to find a 7082 at a good price.

I have now a Victor ql-y44 and a ql-a70, totally happy with those beauties. Please keep in mind the tt-61 to 101 and siblings needs to be kept in their plinths or to have a specially rigid base covering all of their bodies to extend their lifespan.

There are some beauties over here! If Victor is so liked, could we hope one day for a batch of new IC? Some turntables have weight or clamps over them, could it later disturb the IC controling the speed or make it work harder? I know it sound stupid, I am just scare to death about those IC.

BillWojo, so great job! Seriously, with a 3d printer close of you, lot of people would ask you services!

@ Snuck, thanks for the compliments. Nothing 3D printed on my table, all machined manually on a Bridgeport milling machine out of solid aluminum bar stock. Helps that I am a machinist. To bad I still don't have my CNC machine shop, I could make a small batch of those as well as other parts.
That QL-y44 is a beauty!
