FEATURES 1. The TL-922A 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 15 m for SSB, CW and RTTY modes of operation. 2. Unprecedented Reliability The TL-922A 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-922A 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-922A has a double safety system comprised of interlocking switches. One interrupts the high voltage primary circuit while the 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-922A 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-922A 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-922A 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-922A. 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 to match any Trio-Kenwood Transceiver or Transmitter. Your TL-922A can also be used as a high-quality, general purpose Amateur band linear Amplifier with any exciter capable of 80W to 120W RF output.
