Just putting this out there.

I have a 27v DC Trigon Vanguard I Phono stage that I am very fond of but would like to see if it could be improved by a battery PS.

The original BPS are rare and I've never seen one for sale and suspect that price would be silly too.

Is getting a bespoke custom jobby doable and where would I be advised to seek this out from?

I'm looking to lower the noise floor if possible.

Cheers
