Line frequency conversion?

I have a CS506 that was originally purchased in the UK, so is 240V 50Hz....

I now live in the USA and have a transformer to convert voltage, but the line frequency is 60Hz... hence the motor runs at about 20% fast.

I believe the user manual states that frequency conversion was simply a matter of changing the drive pulley. Can anyone advise where I can get hold of a drive pulley?

Thanks, D.O.

Dual 506 Stylus

What is the right stylus for a Dual 506 Turntable?
Where can I get a copy of the service manual in English?

dual 506 stylus

did you ever find out what stylus will fit this model?

Dual 506 Stylus

I don't know if anyone answered this. Here's what I have on my,
still running, CS-506 turntable:
An Ortofon ULM 55E cartridge with a Dual Dn 155E stylus.
I vaguely recall that this was a custom model made by Ortofon for
the 506. I don't think it went with anything else.

stylus and cartridge

I have an ortofon vms 20E MkII which are still available as are copies - google to find. I was advised an audio technic 95E (AT95E) would also suit.
