[Elecraft] Always maximum ALC reading when pressing the PTT on your mic in SSB mode

Hi All,

Just wanting to share a mistake I made this week:

Observation:
When pressing the PTT on your mic in SSB mode, the ALC reading shows
immediately 8 digits illuminated.
There is no power control possible.
Output in SSB is only 1-3W, whatever the mic settings
In CW mode, where the ALC is not effective, everything is working just
normal

Cause:
On the SSB pcb, D2 was incorrectly inserted. The component Anode-Cathode
direction was ok, but it was physically completely shifted 1 hole to the
left (left and right across the marking D2).
