The Hammarlund HXL-ONE Linear Amplifier manual provides detailed instructions for setting up and operating the amplifier, which is designed to work with the Hammarlund HX-50 Transmitter and other similar power-rated transmitters or transceivers. It includes troubleshooting guidance, emphasizing the amplifier's self-contained high voltage supply, control circuitry, and metering arrangements, along with safety warnings for handling electrical components.
Manual Overview
The Hammarlund HXL-ONE Linear Amplifier service manual provides detailed guidance for technicians on troubleshooting, diagnostics, calibration, and board-level adjustments. The amplifier is designed for use with the Hammarlund HX-50 Transmitter but is compatible with other similar power-rated transmitters. It operates on a grounded grid configuration using 572A/B triodes, which are noted for their high plate dissipation and ease of driving in grounded grid service. The manual outlines the amplifier’s self-contained high voltage supply, standby bias, control circuitry, and metering arrangements. Troubleshooting flow involves checking the control circuitry and ensuring the exciter unit can drive the antenna directly when the amplifier is off. Calibration and adjustments focus on the BAND SELECTOR and INPUT MATCHING SWITCH DRIVE assemblies. The manual includes a comprehensive parts list for board-level repairs, covering components like capacitors, diodes, resistors, and transformers. Error diagnostics are facilitated by the metering functions, and specific error codes are not detailed in the provided text.
Quick Issues Covered
- Diagnose power-up failures with internal high voltage supply issues.
- Adjust bias control circuitry for optimal performance.
- Use schematics for circuit tracing and troubleshooting.
Overview
The HXL-ONE Linear Amplifier is a high-performance, ruggedly built amplifier designed to work with the Hammarlund HX-50 Transmitter but can also be used with other transmitters or transceivers of similar power ratings. It is a “grounded grid” type amplifier, self-contained with its own high voltage supply, standby bias, control circuitry, and metering arrangements. It covers the 10, 15, 20, 40, and 75/80 meter Amateur Bands and is rated at 1 Kilowatt DC input for CW operation, 1.5 Kw PEP SSB input, and 500 Watts DC input on conventional AM or 600 Watts DC input on Controlled Carrier AM and RTTY. The amplifier uses a pair of type 572A/B United Electronics Zero Bias Carbon Plate Triodes and includes features that allow the exciter unit to drive the antenna directly when the amplifier is off.
