                                    3.1 GENERAL.
The 30L-1 is a portable r-f linear power amplifier,
including plate power and bias supplies. It is capable of
1000 watts PEP input power in SSB or 1000 watts d-c input in
CW service with any exciter (such as the KWM-1, KWM-2/2A, or
32S-1) capable of 70 watts PEP output. It covers the amateur
bands between 3.5 and
29.7 me. In addition, the amplifier may be operated outside
the amateur bands over certain ranges of frequency. These
ranges are specified in table 4-1. The power amplifier stage
uses four 811A triodes connected in parallel with cathode drive.
3.2 INPUT CIRCUITS.
Refer to figures 3-1 and 7-2. Broadband pi-network circuits
couple the exciting signal into the cathode circuits of the
power amplifier tubes. The tuned input circuits provide
increased efficiency, reduced distortion, and a better
impedance matchfor the exciter than normally would be
obtained with an untuned input. Tuning adjustments are not
required except for operation outside the amateur bands.
3.3 OUTPUT CIRCUITS.
The plate circuit of the power amplifier is tuned by a pi
network consisting of C32, L9, L10, and C33. Capacitor C32-
resonates the tank circuit at the frequency in use. It is
adjusted by the TUNING control on the front panel. The
four-gang capacitor, C33, is adjusted by the LOADING control
to match the pi- network circuit to the impedance presented
by the antenna and feed system in use. Output from the plate
tank circuit is connected through the contacts of antenna
changeover relay, Kl, to the antenna when the control
circuits are energized.
3.4 POWER SUPPLY CIRCUITS.
Two d-c power supplies and one a-c filament supply are
included in the 30L-1. The amplifier may be connected to a
115-volt single-phase or to a 230-volt, three-wire,
single-phase source. Where practical, the
2 30-volt, three-wire connection is recommended. Power
transformer T1 has two primary windings. These windings are
connected in parallel for 115-volt operation,. and in series
for 230-volt operation. The
6.3-volt secondary winding provides filament power for the
811A tubes through r-f choke L8. It also powers the pilot
lamp in the meter. Another secondary winding applies voltage
through surge resistor R9 to semiconductor rectifier CR20.
This is a half-wave circuit connected to furnish blocking
bias to the amplifier tubes under receive conditions and
operating bias when transmitting. It also furnishes power
for changeover relay Kl. Voltage from the third secondary
winding is
applied to two semiconductor rectifier strings connected in
a full-wave voltage doubler configuration. These strings
consist of CR1-CR8, C44-C51 in one string, and CR9-CR16,
C52-C59 in the other. The parallel capacitors equalize the
reverse voltages impressed across the diode junctions and
protect against damage by transients. The output of this
supply provides approximately 1600 volts d-c under load for
the amplifier tube plates.
