The manual provides instructions for installing, operating, and troubleshooting the RV-6 remote VFO with the TR-6 transceiver, detailing the use of controls, function settings, and maintenance procedures. It includes guidance on tube replacement, alignment, and offers service options for repair and adjustment issues.
Manual Overview
The Drake SCHEMATIC manual provides detailed guidance for technicians working with the RV-6 remote VFO unit, specifically designed for use with the TR-6 or TR-4 transceivers. The manual emphasizes troubleshooting flow, starting with tube replacement as a primary step, since most issues arise from tube failures. Direct substitution is recommended over relying on tube checkers. If problems persist beyond tube replacement, technicians are advised to contact the service department with detailed information about the issue, including external connections and control settings. The manual includes voltage and resistance charts to aid in diagnosing minor problems, but warns against servicing the RV-6 without a thorough understanding of electronic circuitry. Calibration and adjustments are minimal, with factory alignment generally sufficient. However, if calibration errors occur, adjustments to coil L-2 can be made by tuning to the 80.0 MHz crystal calibrator signal. The manual stresses the importance of not altering the cable length between the RV-6 and transceiver to avoid misalignment.
Quick Issues Covered
- Diagnose tube failures with direct substitution method.
- Calibrate VFO using L-2 coil adjustment for optimal performance.
- Utilize schematic for tracing circuit issues and voltage discrepancies.
Overview
The RV-6 is designed for use with the TR-6 (or TR-4) transceiver to allow reception and transmission on a frequency different from the VFO setting of the transceiver, but within the same range. It features a stable permeability-tuned VFO, a cathode follower, and control circuitry, housed in a matching cabinet with a speaker. The manual covers installation, operation, service data, troubleshooting, and alignment of the RV-6.
Specifications
- The RV-6 is designed for use with the TR-6 (or TR-4) transceiver.
- Highly stable permeability tuned VFO.
- Solid state design with an ELE.
- Cathode follower and associated control circuitry.
- Housed in a cabinet with a 5-inch 4-ohm speaker.
- Dimensions: 5-3/8 inches high, 10-3/4 inches wide, 11-1/8 inches deep.
- Weight: 6-1/2 pounds.
Controls & Indicators
The RV-6 has two front-panel controls: the main tuning control and the RV-6 FUNCTION switch. The main tuning control determines the frequency of the VFO and is calibrated similarly to the transceiver VFO. The RV-6 FUNCTION switch has four positions: OFF, RCV, RCV/XMIT, and XMIT. Additionally, there is a VFO indicator lamp located directly above the main tuning knob, which lights up whenever the RV-6 is controlling the frequency.
Installation / Setup
To install the RV-6 with the TR-6, plug the RV-6 into the RV-6 jack J-2 on the bottom of the TR-6 chassis. It is necessary to bond the RV-6 chassis to the transceiver chassis and to a good ground with a short piece of braid.
Operation
The RV-6 has two controls: the main tuning and the RV-6 FUNCTION switch. The main tuning control determines the frequency of the VFO and is calibrated in the same way as the transceiver VFO. The RV-6 FUNCTION control has four positions: OFF, RCV, RCV/XMIT, and XMIT. In the OFF position, the unit draws B+ and filament current but does not provide any output, allowing the transceiver to operate normally. In the RCV position, the RV-6 determines the receiving frequency while the transceiver VFO determines the transmitting frequency. In the RCV/XMIT position, both transmit and receive frequencies are determined by the RV-6. In the XMIT position, the RV-6 determines the transmitting frequency and the transceiver VFO determines the receiving frequency. The VFO indicator lamp, located directly above the main tuning knob, lights up whenever the RV-6 is controlling the frequency.

The RV-6 combines classic tube technology with straightforward controls, making it an excellent choice for both beginners and experienced users seeking quality amplification.
Main Features and Specifications
- Output Power: Approximately 6 watts of audio power
- Tubes Used: 12AX7 preamplifier and 6V6 power amplifier tubes
- Frequency Response: Wide audio frequency range for clear sound
- Input Sensitivity: Suitable for various audio sources
- Compact and durable chassis design
- Includes detailed schematic for easy maintenance and repairs
Basic Usage and Operation Tips
To operate the Drake RV-6, connect your audio source to the input jack and ensure the amplifier is powered on with the correct voltage supply. Adjust the volume control gradually to avoid sudden loud output. Allow the tubes to warm up for a few minutes before full operation to ensure optimal performance. Regularly check connections and keep the amplifier in a well-ventilated area to prevent overheating.
Troubleshooting and Maintenance Notes
If you experience distorted audio or no sound output, first verify all cable connections and tube seating. Replace any weak or damaged tubes with compatible replacements. Clean tube sockets and contacts periodically to maintain good electrical connections. Consult the included schematic for detailed troubleshooting steps and component identification. Routine inspection of the power supply and capacitors can prevent common failures.
Safety Reminder
Always unplug the amplifier before performing any maintenance or tube replacement. High voltages inside the device can cause serious injury or death. Use caution when handling tubes, as they become hot during operation. Follow all safety guidelines outlined in the manual to ensure safe and reliable use of the Drake RV-6 amplifier.
