Best Amp out there - some may be as good, but none better! Time Owned: more than 12 months. The SB-220 is one of the classic amps. It is durable, tubes are reasonably inexpensive and available, and it performs for decades. I have had mine, bought used about 20 years ago, in service with the same tubes for that entire time.

Like the SB-200, the SB-220 required updating when the FCC outlawed commercial linear RF ampli-fiers from covering the 10-meter band due to their widespread illegal use on the nearby 11-meter CB band. These later amplifiers were given new model numbers: SB-201 and SB-221 replaced the SB-200 and SB-220, respectively.

The Heathkit SB-220 is a desktop shortwave linear amplifier. It operates on 80-10m and has an RF output of SSB: 2 kW PEP, CW: 1 kW (with 100 W drive). It requires mains power (120/240 V AC) and draws 20A @ 120V, 10A @ 240V in receive mode.

The Heathkit SB-220 is one of the most popular amplifiers ever sold. It was designed in an era when most amateur equipment was based on vacuum-tube technology. Because of this, special care is needed if the SB-220 is to be used with solid-state transceivers.
