Because unfortunately the number of whole stripes for 45rpm are not a multiple of 50hz so this is the closest you get in the UK using this method.

Good enough for most and I wonder do / did record manufacturers make allowances for this?

Update: It works and it was easy to adjust also for a non technican.

One question about the speed of the stroboscop-disc. There is a 33.33 (33 1/3) and a 45.11 (45). Why is it 45.11 and not exactly 45?

Thanks for the advice.

Remember you are 50 Hz

joeyboygolf:

I just use a desk light plugged into the 50Hz mains. Works OK for me.

Turn the appropriate potentiometer until the speed is correct. Easy!

Jow, I use a normal lamp 60 Hz

It is important that the lamp flickers at 50 (100hz) this means a standard tungsten filament lamp should be used. A traditional ballast flo tube would be ok but not modern electronically controlled stuff.

Thanks for the quick and helpful answers.

I've already the schematic...

My questions: Is this job easy to do for a non technican? Which strobo disc i have to use in Europe the 50 Hz? Will the strobo disc work with a Maglite Flashlight?

Best Regards

Upgrade to silver or gold membership and download the service manual. Page 4-1 describes speed adjustment.

You will need a stroboscopic disc, available to buy or download on the internet.

Hi all,

I've bought a second Beogram 4002 Type 5521 in almost MINT condition. Unfortunally the motor run to fast (over 10 seconds per minute). How can i calibrate the speed? All other functions are working good...

Thanks!
