Default Lenco 75????

Hi, has anyone some input on a Lenco 75 turntable. Got one that was piling dust. I want to use it for 78rpm playing/archiving, but cannot find any usefull info on it. Most important, how to set up tracking weight and what is the corkscrew for? (I guess the corkscrew is for anti-skating, but how do you use it).

Also, would it be worth finding someone to give it a complete check? (Or can someone here tell me how to do that yourself)

Yes, the corkscrew is for anti-skating. Trial and error, and good guessing works here. The big weight at the end sets the arm in balance, and you move the small weight to set the force.

OK thanks, got that. So I'll need a test record to get skating straight.

Correct me if I'm wrong: I set the small weight in the middle, balance the arm and then with the small weight set the tracking force. Would 1 division (the rings in the arm bearing the weight) equal 1g?

Haven't seen one in 20 years, but.........yes, the middle (and not so small) one is the balance. I believe the smaller one has 1/2 gram increments. Best my fading memory can conjure up today.

I found someone who had experience with that turntable in a shop. So here are his guidelines for first setup in case I can help someone with it:

1: remove the very small weight with the nylon thread
2: put the small weight (side of the catridge) completely back lined up with the mark closest to the arm pillar.
3: trim the arm to horizontal with the large weight at the back
4: the small weight sets the tracking force, large marks give 1g, the small marks 0.5g (just like you said Jocko)
5: put the very small weight back at the graduated beam next to the corkscrew. The nylon thread should be at the same mark the weight for the tracking force is and put the thread over the corkscrew.
6: the holder of the corkscrew can be turned around the base of the arm. Turn it to be parallel to the beam holding the thread when the arm is in its rest.

Default Operation Manual L-75

Hi here: http://www.nakedresource.com
you can download the operation manual for Lenco L-75 (called Goldring-Lenco L-75)and the protractor aliegment for the stylus. But first you need register en the website.
It´s very important to set up correctly this arm, because you can damage de bearing very slowly and the records too.

Good Luck

Default and also

look for the setting for 78 rpm.

If my memory serves me well, the weight had to be slightly moved to the rear for 78 rpm records

dang a long time ago, I bought mine in 1974 I think in Antwerpen, Radio Star looooong time I remember I was gooing to school and in the summer time I had a job, costed me one month of fulltime work to pay for it Bfr 4750 plus btw, it was my first serious buy I had ever done (about $115) well it was 1974 anyway...

(Apart from the soft plastic material that the arm knife edge bearings sit in. They do disintegrate, and I don't know how to repair them).

My bearings was also more or less destroyed, but I made new ones ,not easy. But it can be done

First I milled a bit of plastic so I had on dimension (wide?) to the right mesuare. then milled a "precut" for the groove. then I took a piece of metal wich was filed to the final shape of the groove, heated it up and melted the groove into final shape. then sawed and filed the the remaining sides. Maybe it could be done without a mill but it will be harder.
