When I moved here to Brazil I did not realize that my old TT was not going to work since it has a 50hz ac motor and the mains is 60hz.
What would be the most cost efficient way to deal with this without buying a new motor (eg Origin dc motors/ps go for 400gbp!)
A PS providing 50hz AC?
Any schematics?

A real simple, good and cheap solution would be to get a frquency controller. Such is very commonly used in industrial motor control applications, and is therefore cheap. You should be able to find a new unit for something like 100USD, and a used for like half on ebay.

I doubt if the output from a frequency contoller is a nice clean sine wave, and a synchronous motor has such low moving mass that it can easily lock to a poor waveform.
There have previously been threads about AC synthesis on this forum. The simplest solution is to use an op-amp oscillator feeding a small power amplifier then a backwards transformer to step the voltage up to drive the motor. If you use an IC power amplifier it really ought to be possible to knock the whole thing up quite cheaply.
Alternatively, why not just find out the price of a 60Hz Linn pulley?
