Default schematic mission cyrus II

Hello, I recently bought a Cyrus II amplifier, but it's not working anymore. I would really like a schematic , and I wrote to Mission Cyrus, but they don't answer. Is there anyone who has a schematic of this amplifier and the PSX? I would really appreciate it. Kind regards,
Roeland De Vriese

The schematics for the Cyrus 1 are on my website -

The Cyrus 2 is basically the same as the 1, the main differences being larger output transistors for the power amp and the addition of a transistor pair at the front of the phono stage.

The psx is the same as the standard power supply, only with uprated components. email me and I will send you what details I have on this.

Default Cyrus II schematic

Hi roebas, Hi Geoff,

Same goes for me, have a Cyrus II amp (with PSX), ob channel doesnt work.
The shortcut on Geoff's thread doesn't work. Any other address available, or got a schematic for me?

It's better to keep your mouth shut and appear stupid than open it and remove all doubt...
