Luxman M-150 power Amp Service manual or bias adjustment prceedure

Looking for a Luxman M-150 power amp service manual.. I have the user manual from here, but it doesn't show or explain any bias settings and I have one channel running a lot hotter than the other after a full electrolytic cap upgrade. Sounds OK just running very hot on the left channel.

Apprecuiate any tips or references... tried google and not turned up too much
