Cello Master Power Supply


Hello,
Does anyone have any info about the Cello Master Supply?
When connected to my Suite or Palette, the power button will not stay in and always pop out.
Any idea what would be the cause of this?
A schematic would be awesome too!
Thanks!

Fairly common occurrence. I would suggest contacting Paul Jason at Viola Audio Labs. Paul has repaired a number of these when he has the time.
Does anyone have a lead in a Cello Master Power Supply (working or not) that might be for sale?

Thanks.
