PS Audio P500 transformer

[ECM]

I have a P500 regenerator I'm rewiring to 230V.

The transformer has dual primaries, but I'm not sure of the wire color codes.

I used a multimeter to check resistance between each wire and this is what I got:

Blue/black 1.3 ohms
blue/white 0.6 ohms
purple/brown 0.7 ohms
purple/gray 1.2 ohms
white/black 1.3 ohms
gray/brown 1.3 ohms

Currently, the way the transformer is connected is as follows:

Blue - Neutral line
Black- hot line
brown - hot line
white and gray connected together
purple - not used

Can anyone shed some light on this?

Thanks

Hi ECM,

Do you fix the voltage?
which you want to to the unit of US model (input :110-120V , output 220-230V)

to the input 220-230V and out put keep the 110-120V?

It's a bit late for a reply, but yes, I was able to convert my P-500 from 115v input to 230v input.

I've been running it this way for over 5 years without any issues.
