Class A schematic for 53VDC power supply?

[laama86]

Hello,

I have -53VDC and +53VDC power supply with 500VA power.

Is there any schematics for those voltages for class-A amplifier?

Schematic can be simple, even so simple, that i can build it without PCB.

Power requirements are between 8W and 50W.

Heatsink size or heat dissipation doesn`t matter. Im planning to use that amp at work so company is paying for electric bills

I searched schematics with Google, but got only amps wich are running between 12VDC and 30VDC.


Any helpo from you guys?

Thanks!

I would modify your power supply in two separate supplies: +53V and +53V. Then use the FirstWatt F3 (it is also known as Zen9 by Nelson Pass) single-end schematics. With high quality parts, especially capacitors, satisfaction is guaranteed.

That sounds excellent!

Do you know where to buy ready PCB:s? I think this amp need PCB:s to build.
I tried Google, but got no results.

Look at the "F3 Builders Thread" at Pass-Labs forum.
