Supereflex Means
MORE POWER PER TUBE
Erla Supereflex makes tubes do
triple duty. One tube actually
does the work of three that
would be needed otherwise.
Three tubes do the work of five,
unquestionably! That is why
simple, compact, inexpensive
Erla Supereflex receivers equal
or surpass the performance of
costliest, temperamental multistage
radio sets.
More power, tube for tube, is
basic in Erla Supereflex. Nothing
else can "make up for it."
Greater power in Erla Supereflex
just simply means finer
radio, which you can afford.
For you yourself can confidently
build these matchless
Erla circuits with Erla Supereflex
CIR-KIT.
CIR-KIT is a complete array
of Erla Scientific Precision Apparatus,
especially created to
make Supereflex possible. CIR-
KIT provides clear, simple instructions
for perfect assembly.
Blueprints are full size. The
panel is pre-drilled for you. The
baseboard is marked to locate
every unit accurately. The famous
Erla Solderless Connectors
do away with soldering entirely
.
With screwdriver, pliers and
CIR-KIT you are sure of a set
that will make you proud, both
for appearance and performance.
The cost is very moderate.
Yet the range, volume, selectivity
AND TONE PURITY
are rarely equaled at any price,
because Supereflex does give
you more power, tube for tube.
