Cello Audio LTD.

I currently maintain a Cello Audio system for my cousin (retired neurosurgeon) and desperately need help with schematics for this equipment.
He loves his equipment and doesn't want to replace it.
It is way overcomplicated and I need (right now) a schematic for the internal power supply for the Cello Palette tone control device.
I would love to have schematics for the power amplifiers and the Preamp section also.
Any help would be appreciated.
Does anyone know how to contact Mark Levinson?

I have seen this thing and it is not what I have. This thing has chips in it and what I have is a lot of discrete transistors (and I mean a LOT of them).

Are you addressing this unit?

If so, see this post. As far as I know the power supply of the Audio Palette was similar or the same of the one of the Audio Suite https://www.whatsbestforum.com/thre...to-find-qualified-service-for-it-today.26578/

No, this is the Master Power Supply that provides + and - 30 Volts DC to the 2 external units that have internal power supplies to further reduce the regulated and filtered power to + and - 15 Volts DC (I think). But you are on the right track! The pictured power supply is much simpler than the internal supplies.

I see - you are addressing one of the internal boards of the Audio Palette?

Did you try diyaudio.com? There are some members there that know Cello gear pretty well.

I sure would like to find them, I am just now learning to navigate those forums. I am not very good at searching that type of thing.
If you could find them, I would appreciate it. I am an old dog and normally stay out of forums.
