Allan,
Was that J5, the 3 pin connector
Alan,
You are reading the schematic correctly - yes there should be a
connection between the cathode of D10 and the anode of D9 (check to be
certain they are connected with an ohmmeter first).
If you find the path open, you could install a TEMPORARY jumper between
D10 cathode and D9 anode

Allan,
Fine that you found it - somewhere along the line, the base K2 was
drawing excessive current and the trace acted like a fuse. I can't say
what the original problem was - maybe the power connector was plugged in
backwards, or something 'dumb' like that.
In any case, it is a simple
K2 4670 with 100W and all options was working fine.
Per the recommendation of Microham, I added a speaker jack from J5 to a
stereo plug on the back of the case and now the unit will not power up on
the KPA-100
When I plug in power to the low power jack, the unit is OK, but will not go
to
Allan,
Was that J5, the 3 pin connector point (no header is normally installed
there) on the RF Board near the front center (near the control board)?
If you did everything correctly, it should have no effect on the K2
power-up condition. If you wired to some other place than the 3 pin J5,
