|Korting Dynamic 1030 (mine is a 1031) tube
radio receiver. Actually the radio is not mine at
all! It belongs to a lady here in town. She may
be interested in selling it. This one is currently
on my bench. I checked the tubes and
replaced one. Since the owner had it turned on
prior to me working on it recently, I did not use
the variac to bring the AC line voltage to the
unit up slowly. It now works and is a real nice
|August 2011-- working on 2 vintage tube receivers/phonograph units. One receiver is a Korting
1031 (very similar to the 1030 model) and the other radio I am working on is a NORMANDE Sterling
High Fidelity turn table with AM/FM Short wave receiver. The Normande receiver is a similar type
of circuit and size to the Korting unit.
|This one is in pretty nice shape. It
works very well. I have not
re-capped it (yet) nor have I done
much cleaning of contacts or dust
ect. I tested the tubes and
replaced one tube and it works
fine just like this. I am going to
vacuum up the dust and speak to
the owner here in Elliot Lake about
the recapping. Re capping is a
common step in restoring these
This one has two tuning eyes and
they both work. One tuning eye
works for signal strength and the
other has some other purpose.
I am going to try and get a manual
and schematic. The tube layout is
on the back panel of the radio.
The same owner has given me a
Normande Sterling High Fi 2/616
model nr radio to work on.
I have a schematic and parts layout
sheet for this radio.
It is very similar in layout to this
Korting receiver. Both radios have
AM (Broadcast Band), FM, Short
Wave (6 to 19 mhz for the Korting)
and the Korting has Long Wave
band as well from 150 khz up to
around 400 khz.
One button is missing from the
Korting and I will be trying to find a
|A view of the back and bottom of the Korting receiver.
There is a handy bottom access panel which allows one to get access to the bottom chasis.
Handy for cleaning and circuit inspection. Note the dust on the top of the access panel. There was dust inside the chasis as well! Inside the chasis there is a type
of circuit board and point to point wiring as well. Everything is in pretty good condition. When I took my small shop vac and vacuumed the radio..it actually looks
real good. Plays well too! Great Sound! The old paper capacitors should be replaced ..maybe in a year or two or so but for now..I am going with "if it ain't broke
don't fix it"!!!
|Below are thumbnail photos. You can click on them to expand as necessary and then hit escape button or
back button on your browser.
|Above: pictures of the wiring and components on the underside of the chasis. The paper capacitors should be replaced. They are generally
replaced in many restoration projects of older vintage tube radios. Paper capacitors are sometimes coated with wax. These ones were not.
The resistors are generally left alone unless there is some damage. Old carbon resistors may absorb some moisture and change a bit with
time as well..but generally they are left in the radio. Its a good idea to let your radio operate and play music or something at least once a
month or so. Capacitors tend to dry out with lack of use.
|The photo on the left is a close up
and not all that clear..but it shows
some contacts that have oxide on
them. This is from the Normande
I have electrical contact cleaner
spray to use to remove oxides. It is
particularly important on the
contact points themselves.
In this case..I may wetten a piece
of paper with contact cleaner and
swipe the contacts to clean them
and then wetten a q tip or two to
scrub off the oxidized parts for
I wont spray the contact cleaner on
parts ..unless I have to. Contact
cleaners do tend to react with
plastics and it is a good idea to
use them in a "minimalist" manner.
Good for the environment and
your pocket book as well.
|Hammarlund HQ-180AC page(s) with pictures -- I am starting this article and will write more in the fall
and winter when I start "serious" ham radio and shortwave listening! Winter is about 6 months long
with snow and that is the time I do more bench work and ham operating. HERE IS THE ARTICLE as it
stands now...Sept3-2011 Hammarlund HQ 180 PAGE(S) LINK HERE
|This radio has many switches as you
can see. Many switches have many
buttons. Buttons and knobs and rubber
feet..often go missing!!
This radio is better than most. It has
only the one switch button missing.
Switches are made up of electrical
contacts and electrical contacts get
oxidized. A radio like this one from
either the very late 50s or early 60s
might get by without changing any
capacitors...maybe for even up to 10
years or so..but the contacts should be
cleaned if they are easily accessible.
|Here I am with Q tip in hand. This radio is nice to listen
to. Good rich sound and it is easy to work on as well.
Large open spaces, plug in tubes.
I had to replace the fuse connector..seen to the left just
above the transformer. The old fuse holder did not work
and I decided to put in a more common fuse type at the
same time and I will give the radio owner some spare 1
amp fuses that I have around.
I replaced one of the burned out 6.3 vac incandescent
lamps (dial lamps). It was a screw in variety and I just
happened to have a few on hand. It helps to have a large
junkbox full of parts when working on this old stuff.
My wife likes going to garage sales and I when I go along
..I buy drawers with parts such as fuses, knobs, little
bulbs. It all comes in handy when replacing parts in old
I dont get into alignments because I dont have
instructions and the owner just wants the radio up and
It sounds real nice and has LONG WAVE band as well.
Nothing much on Long Wave however..Just some airport
transmissions but one could put up a long wire antenna
or loaded vertical to listen for other types of signals.
Some experimenters operate LONG WAVE and MID
wave..just punch the words LOW FER or MID FER into a
search engine and you will come up with a surprising
number of experimental stations. Some are now
operating around 500 khz..just below the broadcast band.
|I use pure alcohol from the drug store..99 percent proof. Dont drink any though!!! I
think you would not only have a nasty hangover but you might die from that stuff.
One lady behind the pharmacy was very reluctant to give me a bottle. I guess she
thought I was some sort of wino or something.
Anyways..I use pure alcohol and q tips or paper towel wad on a stick to swab out dust
and look over the circuitry. One fellow I have spoken to about vintage restorations
says to use "spray 9" to clean the chasis. I didn't think of that at this time. Its
probably cheaper than pure alcohol.
|Two classic sound movies showing the Korting 1030/1031 receiver listening to the
broadcast band at night.
The glow of the dial and the tubes and the old songs with fading ect..real night time
magic! Reminds me of the late 60s before I got my ham ticket. I would listen to 75 meter
AM operators such as W3CIC and Watertowns little radio. Also WBZ Boston, WCAU
Philadelphia and WABC in NYC. Below is a link to some AM radio station audio and video
of this Korting 1031 in action.
These two files may take a LONG TIME..TO LOAD UP..its not as NEARLY as fast as you
tube. These clips are less than a minute long .LINK CLICK HERE

This one is for sale by the owner. I (Earl VE3AB) can act as sales agent ..email me firstname.lastname@example.org --
price and terms negotiable. I would "guess" that the owner might sell for about $275 or so. But I will let
you speak to her and negotiate the deal. I can answer any technical questions as I have worked on the
radio. It is now in her possession in Elliot Lake Ontario. Possible deliver to Ottawa from Elliot Lake.
