Still need some help SB-104A. Got the display working again with a =
replacement  "A" circuit board. Radio has good output when used with PTT =
on mic, on all bands. No output with key, or TUNE switch. Side tone can =
be heard ok. I suspect the problem is with=20
"B" board. I have checked Q209 & Q210 with a simple transistor tester, =
and they seem to be ok. Also, should terminals 2, 4 & 6 of the HI/LO =
power switch, have any wiring. It looks like there were wires, but have =
been removed.  I can only find terminals 1, 3, & 5 on the schematic. TIA =
for any help in this regard.
