The lowering or not lowering of the tonearm depends on the weight of the cartridge
Is there a pickup cartridge on the tonearm?
Has the tracking force been set correctly?

Hello Martin,

Yes there was a cartridge on the tonearm.  During the cleaning process, I removed the counterweight as the whole turntable was very dirty.  I had not replaced it properly in the arm and I think this was the problem as when I did my checks over everything to try to source the fault, I noticed this and then the problem cleared.

Many thanks for your reply though.

Make sure you got it 100% correct.
Use a tracking force gauge.
A few grams (or even tenths of grams) off may not seem like a lot, but it could easily shorten cartridge life considerably.

Hello Martin,

I've just had a close look at what's happening.  When the arm comes across over the record, it lowers but does not make actual contact with the vinyl.  The anti skate then brings the arm back to the rest position.  Is it possible to adjust the set down  height of the arm?

I understand what you're saying about the tracking weight, I set it to 1.2g with a digital scales as per cartridge spec. (MMC20EN)  However, I am not sure what the screw at the rear of the counterweight is for, is it a calibration for the tracking weight scale?  I see there is a cut-out in the tonearm plastic for accessing this screw.

Thanks in advance,

Michael

I worked out the tonearm is the same as on the Beogram 2200, so downloaded that manual.  There, I found out that the above mentioned screw is for balancing the tonearm.  So I balanced the tonearm and set the tracking weight properly and the arm plays correctly now.

However, sometimes when I press 33/Play, the platter rotates very quickly (about 70rpm) and I don't know why?  Can anyone please help with this?

Thanks in advance,

Mike

Yes.
And there's also an adjustment for the tonearm height, the tiny pin that lifts the tonearm is adjustable from inside the counterweight house.
It's all in the servicemanual.

Thanks Martin,

Any thoughts on the high speed rotation?  70rpm at times, an intermittent problem.
