Odds are the 9-69 is the latter module ( higher part ## ).
Why it seemed to come up randomly & never took
over is beyond me. The 9-27 goes back to the first
4 tube hybrid ( B line) through the last hybrids in F-line.
9-69's seemed to pop up randomly but they may have
been used on specific runs for unknown reasons. or
use was stopped for unknown reasons.
