Hello Andries!
I've sent you the 22520 shematic as I feel it could be similar to the one you're looking for.In stereo it is quite normal,but certainly not in mono!The L and R signals are shorted before amplification(this is normal of course)but then :R channel volume pot is disconnected and instead connected to the L signal coming from that channels triode output,so only the L ch volume pot is controlling the volume and the R ch is sort of following....
To complicate things both speaker outputs are shorted and fed to the main speaker and the three treble speakers...
Is all this done to save on speakers(there are no R ch speakers built in)or does someone have another explanation?
