Consonance cyber 211

Hi.
I have a set of consonance cyber 211.
They used to work fine, but now the output volume on one og the amplifier are lower than on the other. Sometimes it's totaly silent, and you have to turn it off and on again. Tubes testede ok, bias ok.
Any sugestions? Could anyone help me with the schematics for this amplifier?
Regards, Kent
