Not to burst your bubble but Euro is 50Hz
even during the 60s?

*ulk*
time to call Andrew Sevilla
PS. i'd love to have a Lenco forum here in WS! thanx for the gesture, Lito

Yup. electrical distribution here is patterned after the US, which is at 60 hz

is this the same as the speed detector sold by Super Jen?

Hi Paul,
You knew what you were doing. I was about to leave when I posted the caveat on the Lenco motor and forgot to mention, I'm anxious to see the outcome of your Lenco project!
Incidentally the book Swiss Precision is a good reference for vintage idler turntable aficionados. It focuses mainly on The TD124, a couple of pages on the EMT and then Garrard 301/401, Lencos, Braun, Rek-O-Kuts as well as vintage Ortofon and SME tonearms.
Back to.......
50hz vs. 60hz
According to Joachim Bung, the author of Swiss Precision, only a handful ROKs were imported into Europe. This explains why when I registered at Lenco Lovers I received a few PMs from Europeans who want to try the cheap ROKs in the USA. However because of the permanently attached phenolic type pulley, there's no easy way a US spec'ed ROK can be made to work in the EU. Similar dilemma as the Lenco. So logically for the budget conscious; 50hz world can opt for a Lenco while 60hz citizens should consider a ROK.
As Joel said, it is not as simple to design a frequency converter for an idler type turntable. Compare the size of a belt drive motor to an idler drive, it is a no brainer.....
je.

re the question on a GL75, methinks this is the rebadged "Goldring" Lenco hence, the "G" added to the L75

What do you think, guys?

With a digital tachometer you can set the speed lever to the appropriate taper in the pulley. Once you know where 33 1/3 & 45rpm is along the speed lever travel, you can reset the 'speed locks'(pardon me for lack of better words). There is no need to machine the pulley down. Mark the new location of 33 1/3 & 45 rpm with decals.

There are a few answers, here's the link http://www.lenco-lovers.com/forum/viewtopic.php?t=867
Voltage, the good news is some motors can be connected for both 240v and 110v
The bad news is how to tell if you have a dual voltage motor, i will keep reading.
For frequency, they suggest a simple mechanical answer - turn down the tapered spindle by 20%.
However, i still think my first idea is worth a try, look at his spindle measurements for 33 and 45 rpm on both shafts, it must be possible to adjust (sounds better than bend?) the idler wheel arm to run on the correct diameter for the required speed.
Or just connect the motor (if dual voltage) for 110v and adjust speed to suit ignoring the speed markings on the deck
My only worry now is if it's as simple as i think, why hasn't anyone done it this way before????
