Lenco / PTP Solid12 turntable

Hello,

Has anyone here had experience with the PTP Solid12 turntable? It's a table based on a re-worked Lenco L75. I'm curious to know how good the speed stability is, basically, does it take a while to warm up, the the speed drift over time, etc.

Also, would love to hear your impressions overall on the table.

G'day,1st I have to ask if you're aware of the site Lenco Heaven and if not, join up as it's a great site and full of helpful advice and ideas.

Off the top of my head I can remember about a half dozen members here who own L75s but in your title you should have mentioned the name Lenco and you would have received a few more replies. The only reason I read it was the mention of PTP and it made me curious as to whether it did in fact refer to the Lenco Pieters Top Plate which I am thinking about getting.

I have 2 75s and a 78 so could be considered a fan of the breed. Do you have one or just considering it?
 
I'm just considering one right now. I know, I probably would have received more hits if I wrote Lenco, but I'm only really interested in the PTP version. And I have checked out Lenco Heaven, but was hoping to hear from some others.
 
If you go to Lenco Heaven and look up PTP you will see what they have to say about them. There's a whole section just on PTP builds including the Solid 12. It is built by Peter Reinders I believe that's his last name. He is out of Amsterdam. He is the farther of the PTP. He makes a few different PTP (Peters Top Plates). It is based on a Lenco motor and parts from the Lenco in his own Custom Plinth. I do not own one but I do own 4 Lenco's one that is a PTP clone and it is an awesome table. So nice I'm considering replacing my 124 with it.
 
I think Lenco L75s abd L70 are great turntables with enormous potential. I have a restored L70, which is obviously not a PTP but I have never experienced issues with speed stability. Mine gets right up to speed and is solid once there. Not sure why a PTP-type would be any different.
 
I own a PTP solid 9. it is without a doubt the best tt I have owned and I have owned a number of nice turntables - Linn, Vpi, clearaudio amongst others. It doesn't take anytime at all to get to speed and speed is completely consistent. The idler drive eliminates any cartridge drag and the music comes alive. It's like all of your lps are 45 rpm audiophile pressings.

Highly recommended
 
Peter is a great guy, who builds a great product. It has received very good reviews. The Lenco design is amazing in its simplicity; and Peter takes a great things, and makes it better.
I have four Lenco/Bogen-Presto decks, and consider them to be top grade products.
 
My understanding was that earlier versions of the PTP provided no way to disengage the idler wheel from the spindle.
Does anybody know if that's correct, and if yes is it true for all subsequent versions?

I have several Lencos (one is my main TT) but never pursued the PTP because of that....

Edit: Never mind, there is a way to do it on PTP2 forward:

Very cool. How would you compare the PTP and Linn specifically? Were there pros and cons to each one?

It's like trying to compare apples to oranges. There both completely different tables. Ones idler and one is belt drive. One is suspended one is not. My choice would be the PTP by far. There are no cons to the PTP.
 
I have a Lenco with heavy plinth, new bearing, double platter, speed controller etc. How would you compare the PTP version, with all other variables held the same (bearing, platter, etc.) Does the replacement top plate make a noticeable difference? The PTP definitely makes a great appearance.

As has been said , Linn and the PTP are different animals. To my ears the PTP is vastly superior. The Linn is belt driven and is similar to all other suspended belt drive turntables. The idler drive provides music that is so much more alive. The lack of cartridge drag delivers a vastly superior presentation. The improvement is most apparent -at least to me - with acoustic instruments that have percussive attributes. Piano, Guitar, Violins etc examples of acoustic instruments that have percussive attributes. A violin section on the ptp comes alive. With all of my belt drives there was always a degree of smear that the idler drive on the ptp eliminates. This is my experience - your mileage may vary!

That is a very nice looking table. Hard to know the difference between the ptp and your table. The benefit would be the isolation of the motor from the bearing. Do you experience rumble? I did with my Thorens TD 124 which is why I found my way to the ptp. I loved the sound of the Thorens but could never get rid of the rumble. I owned a L75 lenco 40 years ago and at high volumes ( my preference back then! ) I also experienced a bit of rumble. Again the ptp gives the benefit of the idler drive without the traditional idler drive issues. That being said, I would imagine that your upgraded plinth probably goes a long ways to a rumble solution.

Hi, thanks for the nice words. I don't really hear any rumble. The original baseplate is damped with asphaltic sheet (automotive type) and the top plate is tightly bolted to the plinth. If the primary purpose of the PTP is to isolate rumble, I might try cutting the original top plate on my next Lenco project.
 
That's fantastic. Beautiful workmanship! Thanks for those photos.

I am definitely going to give it a try (I have an extra top plate). I would use a bandsaw to cut, but it looks like the motor cutout is a blind cut. Did you use a handheld jigsaw? A photo of the rest of the top plate prior to mounting would be fantastic. As many photos as you can provide will be extremely helpful. How does the "Off" position work? I know it replaces the 16 rpm position but not sure how it disengages the pulley. I assume there's a separate motor switch (perhaps on the speed controller)?
 
Cutting out the top plate for the motor was a lot of work trying to figure out how it had to be cut to mount it to the plinth and still be solid. I used a dremel for that. The rest of it was done with a jigsaw and hand grinder. The off switch is control by a micro switch. When you put it in the 16 speed location it will shut off plus it also will move the idler wheel away from the motor. I had to custom make the plinth to work with the motor cut out. switch 007.JPG switch 002.JPG bobs 133.JPG
