Heath Apache TX-1 AF board

Component layout of the Apache speech amplifier component strip.
Unfortunately there is no labelled pictorial in the manual, and
no logical (at least to me) pin numbering scheme.  The following
was reverse engineered from a highly modified component strip -
cannot guarantee it's accuracy, but it works!

The top of the 'picture' relates to the front panel end of the
board.  The left side of the 'picture' relates to the side of the
board nearest to the chassis.

Note:  the (AF ground) and (B+) labels reference wires on the
board, under the components which connect to common ground and B+
points.

Hope this is of some value.  73, Bill  N2BC
