That is one heck of of a circuit description write up!!!
You have not noted what is wrong with the unit but a good tech should be able to narrow it down with that excellent info.
I don't know what's technically wrong, only that the sound is miles from where it should be. I have messed around with the internal bias trim pots, and that has helped marginally, but has not corrected the main problems, hence the need for a proper tech. :-)
