*The Royal Navy Type 182 was a  torpedo decoy system, which has now been removed from service.

These units are the high power output amplifier stage and matching power unit.  Operating frequency is in the range 20-50KHz, and output power up to 2KW pulsed.

The amplifier employs a pair of QY4-250 type tubes in push-pull configuration.  The amplifier chassis also houses the EHT smoothing components, filament transformer, and input/output transformers.

The power supply unit consists of an EHT transformer, a full-wave solid state EHT rectifier, and other auxiliary components.

Specifications (summary):

Amplifier:

• Frequency ~2.0-5.0KHz

• Output power ~2KW

• EHT 4KV

• Weight 33Kg

Power Unit:

• Primary supply 115V 50/60Hz

• Weight 42Kg

Note: while designed for 115V operation, it would be possible to reconfigure the transformer taps for other mains voltages.

Applications

The original application is highly specific, but these amplifiers would be suitable for a variety of other applications.  The following list is intended to give a few ideas, though other possibilities will undoubtedly exist.

• Driver for CW Tesla Coils. (VTTC)

• Plasma tube supply

• Laser supply

• Ultrasonic welding

With modification, these amplifiers could form the basis of a high power RF amplifier for frequencies up to 75MHz, or beyond.

For the High Voltage & High Energy experimenter, these units contain many useful parts.  See photographs and descriptions of the components used in these units.

Once stripped, these components may be re-used for a wide variety of applications, e.g:

• High Power RF amplifiers

• High Voltage/High Energy experiments

• Tesla Coils

Contact with the high voltage components will result in serious injury or death.
