The Steling model F "Little Symphony" is a TRF radio receiver
with a Loften-White audio amplifier. All of the components, which
are large in size, are tightly compacted onto a fairly small
chassis. This same chassis was also used in the Jesse French
model G "Junior" and the Montgomery Ward "Meteor". There is no
AVC and set's volume is controlled by a dual volume control which
controls both the screen grid voltage to the RF tubes and the sensitive
of the antenna coil. A common problem with this radio is that the
windings for the rectifier tube's filament typically short to
ground. An easy remedy for this is to replace the rectifier tube
with a solid state rectifier mounted in an empty four pin tube base and
a 800 ohm/25 watt resistor between the rectifier and the filter
choke. If the filter capacitors are replaced, they must be
replaced with capacitors of the same values as the original filter
caps. Using replacement caps of a larger capacity will result in
a much increased B+ voltage. I aquired this radio from an ebay
auction in November 2009.
