There is a second pair of change-over contacts on the
relay, but with both outputs wired together...this would seem
to suggest some form of muting effect that deals only with
the T/R or R/T changeover period. Any ideas?

The same cct is used for both RX AGC and TX ALC and
it looks as thought the change-over time between sets of contacts
is used to discharge the cct in preparation for the other mode.

Anyway, anybody done maintenance and know the answer to
lifting out the main board? (The Maintenance Service Manual
offers no help in this regard)
