Just taken delivery of another record player I definetly don’t need.
Bit confused as to how to power the thing as yet as it appears to use some sort of switching power supply. I was thinking it would be easy enough to make an external Psu but it wants 168vac that also includes 20khz pulses.
Looking at the power board schematic it doesn’t exactly specify the Ac voltage it wants so I was wondering if these were ever sold in the United Kingdom or if it’s fair game to pipe in 240vac or should I just buy a step down transformer ?

As I understand it from the service manual the power supply board is part of the unit, and its 110Vac only.
Are you missing the PSU board?

The PSU is, according to the manual, specd for 110 V. The circuit is a comparatively simple
switching supply, providing 20.5V and 5.1V DC to the rest of the circuit p. 20 of the service manual
Using a simple 230 - 115V autotransformer is the simplest way of providing the correct voltages,
you only need around 20VA.

Says DC 168, not AC.
168V of DC is familiar in 120V lands as the peak of the wall-wave.
It has a PSu board inside but i was wondering if there was a UK specced one that was suitable for 240v or if it would be easy to mod it internally to work on 240v ?
