Now, according to the block diagram, phones feed (in "main mix" mode) is from after the volume control, after the insert points. This means there is exactly one op amp, an attenuator switch, and a minimum of wiring between it and the outside world. It's possible that someone's done something stupid, like plug a power amp output into a console out, but I'm betting on the -10/+4 switch having some bad contacts (which would not stop it if the circuit were as the diagram states, but I don't trust it as a reliable guide to the actual electronics, just the flow path).

The block diagram is in a pdf I downloaded from the web; it's too big and complicated for a worthwhile attachment. If you PM me your eMail, I'll send it you.
