January 1930
was not long after
Black Friday on October 29 of 1929. Buying radios was not at the top of
everyone's priority list as most of the country scrambled to batten down the hatches for the
economic storm on the horizon. Many top pundits thought the disaster would be short-lived, but it
lasted for more than a decade. It took World War II to finally end the national malaise. The photo
of the Steinite 102-A
radio was found on the RadioMuseum.org website. It is a fancy console (floor) model.
Steinite 50-A and 102-A Radio Service Data Sheet
On the terminal strip of this receiver are mounted: the power-cable lugs; the grid leak and condenser;
the detector-plate bypass condenser; the two center-tap resistors; and the 600-ohm and 2500- ohm "C-bias"
resistors.
A special input circuit is used on the Steinite receivers, for the purpose of obtaining sensitivity.
The circuit acts as an autotransformer when the antenna lead is connected at the junction between L1
and C1. The purpose of R1 is to complete the D.C. path for the grid bias.

Any hum which may develop is ordinarily trace able to the detector; particular care taken in the
selection of a detector tube when first setting up the receiver will result in best operation over an
extended period.

Radio Service Data Sheets
These schematics, tuning instructions, and other data are reproduced from my
collection of vintage radio and electronics magazines. As back in the era, similar
schematic and service info was available for purchase from sources such as
SAMS Photofacts, but these printings
were a no-cost bonus for readers. There are 227 Radio Service Data Sheets as of
December 28, 2020.
