Hi

I finished assembling K2 # 5846 a few days ago and have a problem
that I need some help on.
After finishing the initial alignment I could hear signals on several
of the bands and had transmitter output. During the final alignment
the display started burning too bright. I found a solder bridge on
the J7 connector that was shorting the outputs of the 8 volt and
5 volt regulators together. This was causing both regulators to be
putting out 8 volts. I cleared this up and was proceedng with the
alignment when I notice that U6 on the control board felt warm and I
had lost voltage on most of the components on the RF board.
I turned the rig off for a couple of hours and when I tried to turn
it back on, it wouldn't power up. I checked F1 and it has 12.8
volts on both pins.
Anyone have any ideas?
