I'm working on Alignment and Test Part II. All resistance checks have
been normal, frequency checks are normal, side tone works great. Just no
sound otherwise. I wired up the speaker just to see if it was my
headphones. Still nothing. Voltage checks are within specs except for
the following:

Control board U6 pins10,15, & 24 have 0vdc instead of 5; pin 25 has 5vdc
instead of 0
Control Board U9 pin 1 has 0vdc instead of .4
Rf Board U1 pins 9, 10 have 0vdc
RF Board U4 pin 5 has 0vdc and pin 7 has 5vdc
RF Board U5 pin 1 has 5vdc and pin 2 has 0vdc

I was getting cross eyed checking and rechecking so I've set it aside
for now.  I did manage to find a mistake on the front panel that caused
the ELE message to appear on Alignment and Test Part I, but I'm stumped
so far on this problem.
Thanks,
Bob WB0BS

I took the afternoon off and rewired my bedroom. Took me fifteen minutes
going over the control board tonight, to find the unsoldered capacitor.
It's alive!!  :-)

I can see it now in the "troubleshooting" section:

1) Check all component placements.

2) Rewire Bedroom.

3) Check solder connections.

Congratulations!
