Thank you for the compliment (I collect them).
I suppose restoring classic cars is similar, one can wind up
replacing nearly all the parts and come out with what amounts to a new
car that looks like something from the past.
Even if the old components (of a radio) were the best obtainable
when it was originally built many would have worn out or aged badly and
they were often NOT the best available but those which met the economic
necessity of competitive marketing. So, we replace virtually all
capacitors, sometimes even the longer lived ones, and nearly all the
resistors and often other components like transformers, speakers, dials,
etc, etc. So, what do we have left that is original? Sometimes not much.
Does the set work as it did when new? Maybe. Sometimes better because
the new parts are better than the original ones were when new. With some
luck the thing will look as it did, or at least close.
If you had experience with something when it was new, and have a
good memory, maybe you can tell where it stands viz its performance.
My first short wave radio was a Hallicrafters S-38B, bought new
after a lot of nagging. For a kid with no experience, it was magic. I
still had its remains until recently. I do have an S-38 which one day I
may rebuild/restore. In fact, the S-38B was a glorified AA-5. It worked
quite well for what it was and was a good introduction. I am not sure I
would have appreciated anything better at the time; too naive (means
ignorant and inexperienced). Did not really know the difference between
AM and CW then. Would have helped if someone had given me a Radio
Amateur's Handbook but not sure how much of it I would have understood.
I have currently an S-20R, which I rebuilt, would have run circles
around the S-38B but I am not sure I would have recognized that.
In any case, here we are restoring ancient stuff, some of which
comprise old dreams. Sometimes what we drooled over in our teens turns
out not to have been so wonderful (including some of the girls I lusted
after) some of it was, indeed wonderful. Actually, my S.O. goes back to
my late teens and IS wonderful.
I would say that Hallicrafters fueled more dreams and lust than any
other brand. Part of their success was to appeal to the dreamer in us
and to make stuff that was not too far out of reach. An S-38B was
attainable while a Collins anything was not really in the same universe.
I see classic cars sometimes that don't quite look real; too
perfect. They are shelf queens, if you drove one you might get a spot of
dust on it; too bad, back to the shop to be cleaned and made perfect
again. Not my taste. At least with radios I can make them so they are
usable. No one must wear gloves to touch the knobs.
Hallicrafters cared about appearance; a lot wound up as movie stars.
They are still attention getters, and, unlike the movie queens of the
past, still look the same. Hail Hallicrafters and what a wonderful hobby.

Logic: Method used to arrive at the wrong conclusion, with confidence.? Murphy
Metal oxide film is not the same as carbon film or metal film. Any
of these is superior to composition resistors. I have never found any
authoritative source saying that composition resistors were superior in
any way.
Heat dissipation and lead size depend on the power dissipation of
the resistor. If you have a problem with resistors running hot use
larger resistors. Composition resistors will start drifting right away.
The are never made in tolerances less than 5% because they can drift
that much from the heat of soldering.
Someplace like Mouser should be good for any type of film resistor
but you will have to make your own list for most receivers. The handbook
parts list is often a help.

A note: Collins took the side tone out of the 32V-3 as part of
de-TVI ing it. The 1 and 2 versions had it. Evidently, it was a leakage
path for RF they couldn't stop. In the past I mostly monitored my CW via
my receiver but if you are working split frequencies you can't and a
decent side tone is a necessity. Some of the old code practice
oscillators, like the Bud, were arranged to also work as CW monitors.
They needed only to sample the RF without a direct connection to the
transmitter.

I always wondered why there was no built-in side tone for CW in this rig.
Possible reasons:
Primarily intended for SSB use?
Primarily intended as a mobile rig?
Expected CW ops to be using the Halli paddle and keyer (with audio)?
Does anyone know?
I have an SR-150 in very nice cosmetic condition.? I haven't used it in
a few years - but I have had it on the air.? I did a little CW with it -
but that was rather difficult w/o a sidetone.? I'd like to get it on the
air again one of these days.
Nice rig: looks good; very quiet receiver.

*Subject:* [HallicraftersRadios] SR 150
Last summer I picked up a SR 150 and matching power supply/speaker. It
was in the typical dirty scratched condition and didn't work. I wanted
to say that Walt's repair manual was invaluable. I did the wash down
with simple green rather than scrubbing bubbles because it was
available. That worked very well followed by the garden hose and a few
days in the summer sun. I sanded the case to bare metal and sprayed it
with rustoleum hammered finish pewter. I recapped the supply and the
electrolytic capacitors in the rig per Walt's doc. I followed the
alignment tips and found that I needed to shift the USB carrier
oscillator a bit to bring up the CW power levels. Thanks Walt, the tips
in your manual are gold. I'm not sure if you were a technical writer or
not, but I haven't seen better service docs. I still need to spend time
on the vfo tracking across the dial but that can come later. I also
added a side tone oscillator as I am primarily a CW op and prefer using
a bug. I made up a little board with a couple relays, one to switch the
grid block voltage and one to switch the audio output from my side tone
oscillator. I now have 12 volts on the key instead of grid block
voltage. This is all easily removable with no non reversible changes and
I leave a printed note with the mod details inside the cabinet in a cool
location behind the bottom cover. I am impressed with how stable the vfo
is and the nice comfortable sound to the receiver in this model. The
first contact was a nice chat with an op in France. Lots of fun!

Good Evening, ? I will second the motion for Just Radios when looking for general resistor and capacitor kits.? Look at Dave¡¯s website and you will see that he even has them segregated in most used value by pre & post WWII.? I have been impressed with his kits.? Certainly beats spending hours perusing Digi-Key and or Mouser trying to build a BOM to order. I have also used Hayseed Hamfest for their can capacitors, even complete radio kits and they are nice as well.? So I would say those are my first 2 go-to places when sourcing caps and resistors for sprucing up old rigs.? ? After saying all that, the higher wattage resistors (>10W) you will have to go to Digi-Key or Mouser to source those. At least that has been my experience. ? Thank you, ? Mike W5CUL ?

You can get a resistor kit on amazon that contains every value you would ever need.? They are all spot on and high quality.? You can get a 1w kit and a 2w kit for 10 bucks each.? The new 2w are so small you can use them everywhere.

FWIW, I wasted some of my mis-spent youth working for a manufacturer of
carbon and metal film resistors. Long ago. Carbon film resistors will
run at red heat without damage except to the conformal coating. Metal
film gives greatest stability and its possible to control the
temperature co-efficient. We made zero TC resistors for NASA
contractors. Carbon film is a standard for commercial use, these days
for anything. The main change in manufacturing is the use of laser
cutters to adjust and trim the coatings. We used carbide saws for carbon
and diamond saws for metal film. As a result of the changes in method
film resistors are now very cheap to make. That was the original virtue
of composition resistors but no more.
Composition resistors are made from a slurry of carbon particles in
an insulating carrier. With time, and heat, the number of contacts
between particles becomes less which makes the value go up and also
increases noise. Composition resistors are noisy, the noise being in
excess of the Johnson noise produced by any resistance. Metal film is
the quietest with carbon film being somewhat greater than metal but
still fairly quiet.

Haven't tried it yet other than for testing.? It works just fine.? I might like the "T2" adjustment process better since it's a "set and forget" method.
50W output is more than enough if the band is in good shape.? When more power is needed, the "Boomer" can be easily switched in!

He wanted to contact Hayseed directly to see if they sold resistors - thus the request for his email/phone no.
AFAIK, he only sells capacitor kits for vintage tube radios. I've bought replacement resistors from standard sources (Amazon, Ebay, etc).
