In
the fall of 2006, I was spending several afternoons during the week
seeking out antique malls and flea markets. I have had a fair amount of
success finding radios at this one particular flea market in
Clarksville, Indiana. Some examples of my finds from this venue include
a Radiola 18, Crosley 715N, and a Silvertone 9000. This fine example
was found perched on top of a large display cabinet, with the meager
price of $4.99. An initial inspection revealed the radio to be
complete, minus the knobs on the clock controls. This style of common
1950's clock radios generally has no appeal to me. Given the price and
condition, this one followed me home.
Repairs were rather simple. The paper and
electrolytic capacitors were replaced, and since the power cord was in
good shape, it was just cleaned. The final electronic repairs where a
though cleaning and lubrication of the controls, and the receiver was
aligned. Like many radios from this era, this radio uses a Telechrom
clock. When powering up the radio, the clock was frozen solid. Some
research online revealed that this is a common problem, due to grease
in the gear assembly that hardens over time. The gear assembly is
mounted in a round copper casing. To fix this I drilled a small hole in
the casing and heat was applied for several minuets using a high
temperature heat gun. While the heat was being applied, some all
purpose oil was pumped into the casing though the drilled hole. Slowly
the clock came back to life. Once the clock was working to my
satisfaction, the hole was sealed up.
The cabinet only required some cleaning to remove
the many black spots. The missing knobs were found at a swap meet. Unfortunately
I
could not find three knobs of the correct color, so they had to be
painted using "Antique White" colored paint, with a final coating of
clear lacquer. Below center: The
