Heathkit sb-220 manual

The following questions and answers might help you to know more about its specs and features so you know what you're getting. Turn the exciter on before you turn the amplifier on but reduce the exciter output to zero by turning the appropriate controls. After you have switched on your new amplifier, place the exciter in Tune Mode; the amplifieras meter at this point should read 0. Slowly adjust the amplifieras Tune and Load controls until the amplifieras meter reads 0.

The diodes that are packaged in the Heathkit SB heat up almost immediately when the amplifier is turned on. Oscillator Schematic only redrawn.

If youave assembled your Heathkit SB according to the instructions that came along with the parts, your new linear amplifier should be completely operational.

This amplifier was engineered to be used with an exciter that delivers watts of Radio Frequency out RF output. If you couple the amplifier with an exciter that delivers less than watts, the amplifieras own output will be decreased, and if the exciter you use delivers more than watts, you risk blowing out the amplifier.
