I'm having a bit of frustration tracing the source of the 8.3 volts feeding
IC 1205. It's clear that this is a standby voltage, since it supplies the IR
receiver and the front panel display driver IC, which in turn pipes the
turn-on commands and front panel controls to the main micro on your digital
board. This voltage loops through to page 46 (Point I) pin 6 but exactly
where it branches off from there is anybody's guess. You see only the +
and - 15 volt lines branching off. The 8 v seems to have dropped off the
map. I'm running out of time right now, got to get to work. I'll look at it
some more later and re-post.



Later.
