Ok thanks for your reply. I Will try that again. I actually tested that before, but I think I had too much weight, cause it became worse. So I thought maybe I needed less weight.
I saw in the manual that the weight of the tonearm "must" be between 8-12 grams.
The tonearm just have metalspring for adjustment so there isn't any real possibility for finetuning the weight.
I haven't had that model but the earlier models has a set screw on the tone arm itself in the shaft that goes down to your reject switch. it is an adjustment to raise and lower your tone arm assembly. that's how you fine tune the adjustment on the needle. Make sure you have the correct needle. norm
Not quite correct, actually there is either an adjustment to change the
spring pretension or you can simply bend the spring slightly to increase
or decrease the tracking weight (not recommended!).
Raising or lowering the tone arm is for the setting of the needle on the
record - if there is no record you want the tone arm adjusted so the
needle/stylus just misses touching the turntable rubber mat.
Another problem can be with the pickup wire - if it is stiff that will
cause tracking problems on more modern records. We replace the original
shielded wire with modern pickup wire as it is far more flexible!
