Kenwood TL-922 Amplificatore
Modello: TL-922
Data: 1977
Categoria: Radio Comunicazione
Gruppo: Amplificatore
Descrizione: Linear Amplifier
                                    1. The TL-922 is a Class AB2, grounded grid linear amplifier
developed by Trio-Kenwood through advanced high-power
technology using two high-performance Eimac 3-500Z power
tubes. It covers all bands 160 m through 10 m for SSB, CW
and RTTY modes of operation.
2. Unprecedented Reliability
The TL-922 is designed to provide stable, high RF output
power for extended periods of continuous use. Engineered
with Trio-Kenwood's advanced circuit and mechanical
technology, the TL-922 employs two rugged 3-500Z power tubes
to their full advantage.
3. Low Intermodulation Distortion
Intermodulation distortion (IMD) is minimized through the
use of negative R.F. feedback.
4. Quick Turn-On
Warm-up is not necessary. The 3-500Z tubes are fast heating.
5. Full Safety System
To protect you against any possible high voltage electric
shock, your TL-922 has a double safety system comprised of
interlocking switches. One interrupts the high voltage
primary circuit while thje second directly grounds the
secondary high voltage circuit. Also provided are bleeder
resistors for discharging the high voltage capacitors and
"DANGER” warnings at high voltage positions. Please observe
all warnings, they are for your protection.
6. Newly-Developed Fan Motor Delay Stop Circuit
To reduce power tube deterioration, your TL-922 has a
newly-developed fan motor delay-stop circuit comprised of a
thermal delay relay. The cooling fan will normally run for
140 seconds (TYP) after power is removed from the unit and
will measurably extended tube life.
7. Mode Switch for Efficient Linear Operation
MODE switching is provided to select between the
SSB Mode for the maximum PEP output with good linearity, and
the CW Mode for low power consumption and heat generation
during extended periods of operation.
8. Linear Amplification Control Switch
This switch is capable of setting your TL-922 in the
straight-through state irrespective of the standby control
on the exciter.
9. Variable Threshold Level (ALC Detector)
The ALC circuit will accommodate exciters of 80 w to 120 w
(nominal) by varying the ALC threshold level. This
effectively prevents overdriving the final power tubes,
limiting the Amplifier to its linear range and guaranteeing
low distortion at maximum power.
10. Two Panel Meters
In adjusting or monitoring your TL-922, one meter always
indicates the (Ip) plate current; while, with the other, you
may read (Ig) grid current, (RF) relative output, or (HV)
high voltage. This facilitates ease of operation of your TL-922.
11. Rigid Mechanical Structure
The die-cast side panels effectively support the weight of
the amplifier against shocks and jarring during
transportation. Recessed side panel handles are provided so
the Amplifier can be easily carried.
12. Vernier Plate Tuning Dial
The PLATE tune dial is equipped with a reduction gear that
facilitates easy tuning, particularly for the higher bands.
It also effectively prevents accidental miss-tuning during
operation. Controls and panel arrangement, designed to human
engineering standards, provide superior ease of operation.
13. Neat, Contemporary Appearance
Mechanical arrangement and sophisticated design match both
the TS-820 and TS-520 Series transceivers. Your TL-922 can
also be used as a high- quality, general purpose HAM band
linear amplifier.
