DIY power supply for Heed Questar MC phonostage

[Ludovico]

Hi.

I have just bought a Heed Questar MC phono stage, which comes with the stock power supply.

I would want to improve the sound by adding a better power supply. The Heed Q-PSU is far to expensive for me, so I would want to build a power supply myself the reduce the cost.

All I have is the input spec: 220 µV/100ohm.

Here is a picture of the Heed Q-PSU power supply:

An externally hosted image should be here but it was not working when we last tested it.

Here another picture of the power supply:

What's the voltage and current the preamp uses?

I made a mistake, it is a 30V power supply.

I found this thread, with many pictures of the inside of the power supply: Phono-Vorverstärker - Phonovorstufe - Heed Quasar - Frank-Landmesser.de

So, what I need is:

- a 50VA toroidal transformer
- Four Capacitors 10000UF-35V:
