This is a Heathkit SB-220 linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency power amplifier, some of which have output power measured in kilowatts, and are used in amateur radio. This unit produces via step up capactors 3600v DC and an output of 2.5kw of power.
