Goldring/ Lenco L99 has a build-in strobe

[Lynnot]

Hello,

I did a quick search but didn't find anything about it: I got myself a L99 and saw that it has a build-in strobe, did not know that.
Speed is slightly off (to slow) and I wonder where I can fine tune speed in order to make it go 33 rpm. spot-on.

Anybody knowledgeable?

Thanks & regards,
Tony

There should be some sort of speed control, otherwise i see no sense in having a strobe.

Hi Tony,

It looks like the speed control is fully adjustable between 16 and 78 rpm, through gearing to the speed selector.  The strobe arrangement works using a mirror to reflect the view of the markings, which seem to be on the underside of the platter or its rim.

My limited knowledge is gleaned from the linked thread - I've never seen a Goldring 99 for real.

Good luck 

Dave

If you carefully prize up the speed control knob you will find four sets of fine adjustment sliders.
Ensure that the bearing is well oiled and the main speed linkage is properly set. Then you fine tune.
Loosen each of the sliders in turn. Use a small pair of pliers to carefully set the position of the knob shaft at the correct position as you watch the strobe. Lock the screws down when you’re happy.
If your room is at a constant temperature then you should only have to do this once a year, perhaps. Then any serious change in speed will show up a different problem - idler slippage, dirt etc.
Extremes of temperature change will need a more frequent adjustment.
It is possible to remove the sliders so that the knob does not lock, which is useful if you want adjustable pitch

Are you sure??
If it resembles the posted image - it's a 'G99'.
Mine has a rotary speed control which you just turn until the correct speed is obtained.
There's no sign of any 'adjustment sliders' on mine and none that I can see in the attached image.

I have a G99 and found this also – its speed adjustment is described as 'infinitely variable'

I'll admit to never having tried to prise the rotary speed knob off. Old plastic gives me the heebie jeebies

It did occur to me that it would be possible to place limiting stops in one of the sliding linkages, a bit like the PTP...

Following the thread with interest

That's because early G99's didn't have "click-stops".

Well done, Wout.
The stops are optional, & a later refinement.
I apologise if I have confused anyone!
It appears that my 99, one I restored & two that I’ve had for repair, were all later models. I’ve never met a Mk1…
It’s useful to have the correct info here now!
