This paper dial scale will be used to insure proper positioning of the
tuning indicator. An exact size is not needed since the number
position radius is maintained with any scaling. |
The challenge for this restoration is the tuning gang. It will
need replaced or repaired. This should be no big deal. |
This appears to never have been worked on. All caps (except
ceramics) and resistor get replaced. I do not want this send back
due to a changed 10 cent resistor. |
|
The rectifier tube 35Z5 tested good in the tube tester. It does
not work in the radio. One half of the filament is bad. |
Look for the scrapes on the right gang. These bent veins
short.
|
I did not have a replacement in the
garage. So on to repair. First is to sand off the metal burrs.
If I meet with failure then I would find a compatible replacement on
the eBay. There is nothing to loose at this point.
|
I used a long razor knife and a flashlight
behind the gang to look for touching plates. Also A DVM with the
continuity beeper helps.
Patients and care yielded success!
Officially this is called "Knifing". No Joke!

A good washing in the sink with Clorox
Clean Up and a tooth brush. The brown plastic is in good condition.
These knobs were dirty.
The gold paint is a bit rough.
|
| After 30 minutes warm up/burn-in the
alignment begins. Tubes and parts heat up and drift for a
while. It is SOP.
A full electrical alignment has been completed. And the radio is
happily playing away. This begins the "burn-in"
period. |
Mask off the centers. |
Spray with Testors Gold. It looked to be the closest match. There
is also GM Gold that is a bit less yellow and a bit on the copper
side. |
 |
Looks nice. |
Tony Bennett sounding great! 10PM starts old time radio
stories. The Tails of the Texas Marshals is on first. |
Cleaned up chassis and tubes. |
Gotta have a night shot of the glowing tubes. |
The only thing left is to
receive the Isolation transformer, connect it to the line cord and
burn-in. Well nothing should "burn". It just means
to run the unit for a time period. If there is anything to
break. It is best to happen here on the bench and not with the
owner. |
The new 50va Isolation Transformer on the left.

The chassis consumes 28 watts.

This is a video of radios that are being interfered with. The
station at the low end of the tuning band about 540 has another near
station on the same frequency. It sounds like a howl. Up the
band a high pitched whistle is heard. That is common interference
heard mostly at night.
Even an expensive ham radio transceiver can not eliminate the lower
howl of two radio stations on the same frequency. |
More advanced radios have
whistle filters that reduce this higher pitched sound. |
