Yeah I believe that container holds the hybrid output amplifier. I looks as if it may be the Achilles heel. Check the link to the guy that reconstructed and made a replacement. There is a lot of useful information there.
Also, if you look at the diagram for the output amp, the -6.3v is only switched in at the +20dBu attenuator setting. I believe to get better linearity at the high level setting.
