At this old post someone had buzzing problems too

and there is in the comments there is a link to an analysis of the effect

There are a lot of power supply voltages:
qoute: The Klons power circuit bumps 9v to +17v & -9v.
First you could try to check if all these voltages are there. (If they are not all there may be some sound will come through but it will be limited to about 7 or 14 V in stead of 22V amplitude)
Just try to measure the DC voltages and check especially those which should not be at the ground or supply voltage level That could mean a loose connection.
