Default WTB : Power Supply Board for ONO Phono preamp Clone (From Group Buy)

This is a real long shot but I am looking for one Ono Clone Power Supply Board.
Can be with or without components.

I want to make my ONO phono preamp a dual power supply model. Currently it is a single PS board supplying both channels.

Let me know if you have anything available to sell to me.

Thanks in advance,

Hi Dan ,

maybe Zen Mods Shunty for X-Ono is the Solution .

So you would say a shunt or series Active Regulator (based on 317/337's) with separate regulators for each channel would be much better than the existing ONO cloned PS?

Options:
What would be the best from the following group:

1) An intermediate 317/337 regulator circuit to bring voltage down from +/-44V (using 32VAC+ 32VAC secondaries) down to +/-40VDC and then leave the existing ONO PS as the final from +/-40VDC down to the +/-30VDC voltage. This would include 40KuF raw unregulated voltage (using MUR 860/1560 series of fast/soft recovery diodes prior to the 317/337 circuit. Basically Dual stage regulation

2) Dual Shunty Regulators - one for each channel

3) Dual Existing ONO PS (mosfet-based)

4) Or?

Let me know.

Thanks in advance.
