Building high-end 'tables cheap at Home Despot II


“For those who want the moon but can't afford it or those who can afford it but like to have fun and work with their hands, I'm willing to give out a recipe for a true high-end 'table which is easy to do, and fun to make as sky's the limit on design/creativity! The cost of materials, including 'table, is roughly $200 (depending, more or less), and add to that a Rega tonearm. The results are astonishing. I'll even tell/show you how to make chipboard look like marble and fool and impress all your friends. If there's interest I'll get on with this project, if not, I'll just continue making them in my basement. The next one I make will have a Corian top and have a zebra stripe pattern! Fun! Any takers?”

Let the saga continue. Sail on, oh ships of Lenco!

To everyone who has been involved in the custom topplate project: They're in!!! look at the lenco lovers site for pics.
Great news Peter, it's Christmas!! I look forward to handling these beauties myself, using one as a platform for my "Lenco-Noll," contact me for shipping, moneys owed and so forth.

And up here it is going to be an Audio Christmas for me, as I'm allowing myself a few days to play with my new and old toys. Through a lot of complicated horse-trading I have acquired a VPI JMW 10.5 for my Decca, and this pairing is singing sooo sweetly on my Lenco!! The Decca is slamming and induces the Kundalini Effect, to the extent the ESS can manage it, I'll be setting up the Fabled AR2ax's (they are the seismographs of PRaT) tonight to get the full brunt of the Kundalini Effect in swing in time for Christmas!!

I'll also re-wire my new/old Rega RB-300 and test it out with a variety of MCs to see how it rates/compares against the Morch UP-4 (a fabulous match for the Garrard 301 btw), and also set-up the MAS with a variety of cartridges to see how IT rates against the various Giants inhabiting my plinths!! I am still blown away by just how good the MAS sounded with an ACE recently at a buddy's place, exactly the same strengths as I heard when it was mounted with my Grado in my own system: dynamic spread and dynamic speed/acrobatic alacrity, and ensuing clarity, which proves that detail/information-retrieval is GREATLY affected by the successful retrieval of macro- and micro-dynamics.

For those who have MAS tonearms, this tidbit of information from a necessarily old review of a MAS ‘table/MAS 282 tonearm dug up by a local. It also shows just how deep the understanding assumed by the reviewers for the readers in a world in which record players were the chief source, a different world from today:

"The indicated vertical tracking force was accurate to within 0.1 grams. Although the anti-skating is adjustable only in 0.5-gram steps, it proved satisfactory, since skating compensation can only be approximate anyway. The arm-cueing was well damped, providing a gentle descent of the stylus into the groove with no sideward drift. The arm exhibited very low pivot friction and no detectable play, a result which is consistent with the claimed bearing tolerance of only 10 microns. The capacitance of the tonearm wiring was measured as 100 pF in each channel...The tonearm’s infrasonic resonance was assessed with a Shure V15 Type IV phono cartridge. Since the MAS-282 tonearm has vry low pivot friction and no provision for damping, the arm/cartridge resonance was very pronounced, rising to a 30-db peak at 11 Hz with the Shure’s damping brush disengaged. Engaging the damping brush brought the resonance down to a 10-db peak from 15 to 19 Hz. One of the major byproducts of an undamped resonance is exaggerated cantilever deflection in response to surface irregularities and disc warps, and a consequently large variation in the effective vertical tracking force that acts to hold the stylus in contact with the groove...Therefore, it is recommended that the MAS tonearm be used with an external damping device or with phono cartridges having internal damping. (This advice, of course, applies to all tonearms that have low pivot friction and no provision for their own damping.)...Most important of all, the reproduced sound was excellent. Even with thunderous bass levels the instrumental textures were clearly defined, the background noise was very low, small details were heard with exceptional transparency, and the stereo image was both deep and stable.”

Lots of interesting stuff there to absorb and cogitate on, enjoy a look back at a World of Vinyl all, and once again, have fun and Merry Christmas!!
You've always talked about the importance of mass, yet you didn't do the obvious and put the white Lenco on the red plinth!? Christ-mass plinth! :-P

I sort of forgot, but will send the stylus to poor Dave in the beginning of the happy new year!

Merry Christmas all Lenco-thread-ers!
Merry Christmas everyone...haven't been on the thread for a while-been Lenco-less for quite a few months now. Decided to treat myself to a new cartridge as a Christmas pressie as its been far too long since Ive been able to spin that vinyl. So, this afternoon (yeah, Santa came early in downtown Surrey-well...I wanted to wake up on Christmas morning and welcome in Christmas with the albums Ive been collecting this year ready for when my Lenco was back up and running). Started to fit the cartridge, and unfortunately one of the connecters came off. So....down to the garage to dig out the soldering iron...and, to my dismay, found there wasnt any solder. Oh the joy of having teenage sons who use the last of your solder creating a latenight sculpture from empty beer cans and don't let you know its all finished!!
So...no vinyl tomorrow-will have to wait a few days til the shops open again. Ah well....just a few more days for the suspense and tension build up until that final moment when I gently lower the needle onto the groove...and an explosion of sound fills my room...

Wishing you all a very Merry Christmas and may Santa bring you everything you've been hoping for
Merry Christmas everyone. Hope all those idler motors are nicely oiled. Finally got my multi arm jobby out of the garage and posted an update in the all out assault pages. The arms are working a treat, I thought they may be set too close but it it all runs fine and the el cheapo air tube suspension is doing the job brilliantly. Initial sound tests revealed..... major rumbling! Oh dear. After minor panic I remembered that the platter etc had been sitting upside down for six months and all the oil drained out and I forgot to earth the mains. What a dope. Must be going senile. The MG-1 arm is a treat to use with very low background noise levels but has to perfectly level. There's plenty of fine adjustment and it's been great fun to use and is in a different league to the Grace 707. Still haven't resolved the air supply arrangement yet and I think it's going to take another or much bigger pump to prime the surge tanks and regulator properly. The sound overall is very clear & natural with either arms and various cartridges so its promising. There's obviously going to be a lot more tweaking. There's a terrific drive and harmony to the sound overall. The bass is quite thunderous and I've had to roll of the subs so no issues there. Now to get my head around all this valve stuff and build some proper amps to drive this monster.
Happy holidays everyone.
regards
