Check for the #12 bulb inside the PA compartment, on top of the T-R
relay. Make sure it's there, and not open. Also check the relay itself
for dirty contacts.

After spending a while deciding, I am now the proud new owner of
a TR-3/RV-3/AC-3 set. (Also a a W-7 meter, but I'll probably see
if I can trade it for a more appropriate W-4 at some point.)
In any event, there was some minor shipping damage but nothing
major; just some bent cabinet sheet metal. But the real issue is
the set seems to be pretty deaf. I haven't even tried to transmit
into a dummy load yet. (I have a Palstar DL2K so I should be all
set in that area.)
If I hook it up to me HP-8640B and set the TR-3 to receive SSB, I
can find the signal on all bands, but the (AM) modulated signal
is really down in the mud. If I switch the set to AM, I am unable
to find the signal at all.
I also tried to see if I could pick up a 40m signal which was
booming in on my Icom-725 + Cushcraft R7. Using the same antenna
I couldn't hear anything.
So I expect there is also some electrical damage; probably one or
more tubes. My next task is to test all the tubes on my TV-2/C
tester. From there, I'll do all the voltage and resistance checks.
I was wondering if you kind folks might have some other suggestions?
