Installation / Setup

The installation of the HEATHKIT Model GP-11 Vibrator Power Supply involves selecting a mounting location that is sheltered from rain and free from excessive dust. The power supply can be mounted in any position, but the screw terminal strip and both ends of the chassis should remain accessible. Mounting holes are available on the bottom plate, and various types of screws or bolts can be used depending on the mounting surface.

For wiring, only three wires are necessary, and it is recommended to use #16 or larger wire for the INPUT and GND connections, keeping these wires as short as possible. A fuse should be used in series with the INPUT wire for safety, with a 5A fuse for 12 volts or a 10A fuse for 6 volts. The wires should be secured in the plastic clamp next to the screw terminal strip.

The cover installation requires two 6-32 x 1/4″ screws, one for each end of the cover, which should be tightened into the speednut mounted on the chassis. The cover slot should fit over the wires running to the power supply.

For input voltage conversion, from 12-volt to 6-volt operation, specific connections need to be clipped and new connections made, as detailed in the instructions.

Heathkit GP-11 Vibrator Power Supply Manual Overview

The Heathkit GP-11 is a vintage vibrator power supply designed to convert low-voltage DC input into higher-voltage DC output, primarily used to power tube-based electronic equipment. This manual provides detailed schematics and operational guidance to assist technicians and hobbyists in understanding, repairing, or restoring the GP-11 power supply unit.

Main Features and Specifications

  • Input Voltage: Typically 12V DC from automotive or battery sources
  • Output Voltage: High-voltage DC suitable for tube radios and amplifiers
  • Vibrator Circuit: Mechanical oscillator to convert DC to AC for transformer operation
  • Transformer: Step-up transformer integrated for voltage conversion
  • Compact and rugged design for portable and field use
  • Includes detailed schematics for troubleshooting and repairs

Basic Usage and Operation Tips

To operate the GP-11 power supply, connect the input terminals to a 12V DC source, ensuring correct polarity. The internal vibrator will generate an AC waveform, which the transformer steps up to the required voltage. Always allow the unit to warm up briefly before connecting sensitive equipment. Avoid overloading the output by adhering to specified current limits. Regularly inspect the vibrator contacts for wear and clean as necessary to maintain optimal performance.

Troubleshooting and Maintenance Notes

Common issues include worn vibrator contacts causing intermittent operation or reduced output voltage. Inspect and clean contacts with fine sandpaper or replace the vibrator if severely worn. Check all wiring and solder joints for corrosion or breaks. Verify transformer continuity and test output voltages with a multimeter. Replace any faulty capacitors or resistors as indicated in the schematic. Periodic maintenance ensures reliable power supply performance and longevity.

Safety Reminder

Always disconnect the GP-11 power supply from all power sources before performing any maintenance or inspection. High voltages present at the output can cause severe electric shock. Use caution when handling and avoid touching exposed terminals. Follow proper grounding procedures and work in a dry, well-lit environment to ensure safe operation.
