CHCUIT DESCRIPTION Edvl
" ' Circuit Da.ta.,Schematic
The llodel 460 is a seven tube supsrhetsrodyne receiver whose circuit comprises a first
etector, an oscillator, two stages of I. F. amplification, a combined double diode
second dete?tor and first audio amplifier, a power amplifier and rectifier tubs.
Selectivity is provided by a double tuned antenna selector and three double tuned I.I-'.
transformers, comprising eight selective circuits in all. The double tuned antenna
selector is important in the broadcast band for reasons well known, and is all the more
important on the short wave band in order to prevent "repeat points", that is, ~recep-
tion of the same station at two points on the scale.
