and it is not difficult to add 6 tiny piece of magnet and hall senors to build a feedback control speed controller ( may be someone had done it too), especially after add 2nd platter , make things even easier for dynamic balance the overall spinning platters ( if we really care )

what if....the 2nd platter is at 15 inches...etc... don't have to be same diameter too, and it make a lot of sense too

Double platter or any heavy platters could potentially alter the speed incorrectly.

Nigel, a member from Lencoheaven, has developed the speed controller and you can find out the details from the following link:

https://www.lencoheaven.net/forum/index.php?topic=13981.0

I am sure Master HaHa should be able to figure out the whole idea.

Apart from the speed controller I would just use the good old fashion method by checking speed with this strobe speed disc.

Since the motor speed is driven by the motor shaft and it is linear so the speed change is gradual. You can correct the speed and mark it on the speed selector for next use.

I know it is not as cool as having a speed controller but I am just a lazy person ^_^

my speed controller was also based on Nigel's design. Our group made nearly 20 of such controller and some used them for other AC motor TTs too like 301, 401, Cuemaster...

if you search some commercial speed controllers they cost a bomb!

@fotheringay, manual adjust is good but the speed controller has a variable voltage output so lessen the vibration of the motor.

@hahayanyan, get the lenco first and do the speed controller later.
you can mount a bare bone Lenco on cola cans without the wooden plinth and it will sound a lot better than many TTs in the market....but your YMMV...

I seriously recommend all Lenco users to get the Malaysian's spindle bearing! Buy in groups to save shipping cost.

yes, it is a T71 , cost hkd 1600 without arm . start up fast..brake at instant , tight W&F % , but no pitch control

but what more to ask for ...at that cost.. haha , quality decent sound, it performance reasonably well neglecting the price etc.. ,it is a competence drive for the task

haha

It is not apple to apple

But if it is blind test between t101 and the lenco... What may be the outcome?

Fun to know..or even speculation

i have a belt drive TT as well. So many tonearms and cartridges...different combinations...
i wish i could be like Ah Wher with his vast collections of gear. Absolutely mind-blowing!
I don't wanna restrict myself to one style of 'music' playback.
Idler TT is the not the end game for me (not yet)....as always, YMMV

As to your question, when the pandemic is under control, you are invited to hear them yourself :-)

may be about 10 yrs ago, JBL fellow took me to Ah wher 's places at Chai Wan

it was front roll of more than 1 x Micro , and at the back of the wall, there was a Pioneer P3, and JC verdier ( may be 2 of them) , it is quiet obvious a lot of attention was noticed on hows he set up those Micro ...... the flywheel at his best..........

forget which amp was used ,but it was the pair of Rey Audio , rather unique offset horn on a stand

forget what phono stages too

some of the very good presentation i ever listened
