Hi,
I am getting a Hammarlund HQ-145 receiver that will most likely need
recapping and aligning. I am in Martin County, near Stuart, but not
far from Palm Beach County.
Thanks,
Bob Grimes

Ain't much to recap in that one.

Except for the filter caps, mostly disc ceramic caps IIRC.

BTW, that chassis ain't FUSED!!! First order of business.

You could contact an area radio collector club and request a recommendation
for a repairman in your neck of the woods.

That is correct. When I recapped mine, I just had to replace the three
capacitors inside a multi-capacitor can. Two of them were ca. 500
volts in the 40-60 mfd range and were the filter capacitors. In the
same can was a 50 volt capacitor, I think 10 or 20 mfd which was part
of the audio circuit to the 6AQ5. I just replaced them with discrete
components. Everything else I could find were disk ceramics.
After I recapped, I couldn't get the thing to work and was somewhat
frustrated by this as all the voltages etc checked out and I had done
all the tube substitution. What I forgot was that when I took it out
of its case I removed a jumper between the prongs of the relay output.
You either need a jumper, or and actual send/receive relay contacts or
it won't work.
Duh. I discovered this when I got the schematic for the version I
actually had. There was a small modification in mid production when
Hammarlund changed from a tube rectifier (5U4 family) to diodes and I
had a schematic of a later version than the one I had. I the
schematic (got off of BAMA or some website like that) there was some
text which said you had to have the jumper (or relay) or the radio
wouldn't work. I don't remember what the relay controled, it might
have lifted the center tap of the power transformer. I'll have to look
at the schematic again. Recapping was about a 30 minute job, mostly
just figuring out where to mount the caps. I added a 4 our 5 tab
terminal strip with one of the tabs going to chassis ground.
I haven't used the radio at all really. I got it in a rather funny way
about 12 years ago. I went to buy a Heath SB-200 amp that a ham was
selling on behalf of the estate of a Silent Key. I was trying to
negotiate the price downward a bit in the spirit of ham horse trading.
So the fellow agreed to my price which was about $50.00 under the
asking price. He agreed to the lower price by said "But if I give you
that price, you're going to have to take this old receiver off of my
hands and he gave it to me. The few times I have had an antenna on
it, it seemed to work fine, but my memory of how old tube radios work
is a bit dim and these old radios don't have the bells and whistles of
the modern ICOM equipment I have in my actual working shack. A crystal
filter is no match for modern filters of DSP.
Unfortunately I don't have much of a junk box now to throw together a
simple CW transmitter, something I did fairly often when I was a kid
(I was licensed at age 13, I'm now 66.) Maybe I'll have to get into
this as I am leaving another hobby...sailing. My boat was just sunk by
two huge oak trees falling on it while at a dock.
