Although I've been messing with idler drive Lencos for a few years now there seems to be a bit of a forum buzz about 70's Japanese direct drives from the likes of Sony, Denon and JVC so I bought (and recently sold) a Sony PS-6750 which I thought pretty impressive but really wanted a go at something I could try to upgrade - like the flying saucer shaped Denons and JVCs. So this came my way.........

......and it sounded pretty darn good in stock form. In typical Japanese quality of the time all the controls worked beautifully and speed was rock solid. As plinths are pretty easy to cut for this deck I started using materials I had to hand. First up was a "no plinth" set up as I'd read elsewhere that this can work well. It uses delrin legs I made for another TT project.

This sounded much the same as the stock JVC but with a small tightening up in the bass (all comments according to my ears :) )

Next was an offcut of beech worktop.

Actually an improvement over the no plinth plinth. Sweeter and with a bigger soundstage.

........and then to slate which took hours to cut!

I've always liked slate for Lencos - there seems to be a synergy between the two but I'm not so sure with the JVC. It had a more powerful presentation than the beech but I sort of preferred the latter's more relaxed approach. I was thinking then about building a fairly traditional birch ply plinth when a discussion about Permali, Panzerholtz and MU25 (variations on compressed, resin filled plys) over on Lencoheaven got me thinking and after pricing up the options I went for the MU25 which is the least dense of those mentioned and not much different in cost to a bit of decent baltic birch ply.

So finally I've arrived at this.

Arm is a 12" Jelco SA750L with a Zyx R50 Bloom and it's all sounding quite splendid :) To be honest I'm not certain the MU25 is that much better than the beech block but it's been fun trying different materials.

Cheers, Ian

I love the slate plinth, it looks great!

I turned away from idler to direct drive about a year ago, Technics SP10 mk2 with Tenutu heavy mat and a fully upgraded power supply. I wouldn't go back to an idler, whatever make.

Looks like someone needs to open a 50s style diner :eyebrows:

very nice!
where can you buy the likes of Permali, Panzerholtz and MU25? i wouldn't mind having making an armboard.

American diner? Cheek, actually I'll take that although it was supposed to be more Bauhaus :) Re Panzerholtz and MU25 try here http://www.ltlewis.co.uk/beech.htm
Permali is available here http://www.permalideho.co.uk/

cheers for the links, did you buy a whole sheet or can they supply smaller sizes?

Andrew at LT Lewis will look for smaller pieces but Permali will only deal in fairly large and expensive sheets. Best to ring both and ask.

Black and chrome for a Ballhaus look, surely ?

Actually, tubular chrome with some kind of funky leather finish :D

Sure, but I've done the black and chrome before.

Anyone know how much one should expect to pay for these TTs?

Think the buy it now is a bit excessive, around £300's probably about right. I have the A version with different arm lift arrangements & 'photokinetic end of play mechanism' :eek: (just means the arm lifts off at the end of the record).

Thanks Roy, currently in the middle of the 1210 upgrade path, so I was wondering what Jap DD would be a significant step up from a moderately modded 1210!

My QLA7 is imho better than a stock 1210 (I had a 1200) but whether it's better than a modded 1210 would depend on the level of modification.

Too many high end Jap direct drive TTs to choose from!

I cannot understand the fascination with belt drive when there is direct/idler drive.

They tend to be easy to maintain and some sound very good.

And. There is no 'best' type of turntable.

I agree to a point - but rubber belts change elasticity depending on age/temperature and absolute speed/pitch is affected. Even a very slight variance affects transient leading edge and can smear. With direct drive or idler this isn't an issue. This is separate to the best Turntable question. Only my opinion.
