Heathkit SB-220 HF Linear Amplifier 80-10 with CAP KIT + HARBACH MODS NO RESERVE Picture and Description:
Heathkit SB-220 HF Linear Amplifier 80-10 Meters Works well. It has BRAND NEW FILTER CAPS,NEWER DIODES. SK-220 HARBACH SOFT KEY - The SK-220 safely acts as an amplifier interface to your modern transceiver to the Heathkit SB-220 or SB-221. This unit is mounted inside the amplifier and transforms the 120VDC key closure to approximately 0.7VDC at 1.5mA. Without it you run the risk of severely damaging the keying circuit in your transceiver. SS-220 HARBACH SOFT START. The SS-221 limits inrush current during amplifier start-up by placing a small resistive load in series with the AC mains. The load is switched out of the circuit by the relays a few milliseconds later. The soft-start mounts inside the amplifier and safely limits inrush current to protect hard-to-find and costly-to-replace ON-OFF switches, tubes, filter capacitors and high voltage transformers. PS-220 HARBACH PARASITIC SUPPRESSOR KIT The PS-220 kit provides all of the components to eliminate parasitic oscillations that can have disasterous effects on tubes, plate tuning capacitors and the bandswitch. If your SB-220, SB-221 or HL-2200 arcs or spits during tune-up or normal operation, the PS-220 will help cure and stabilize the amplifier. NOT AVAILABLE ANYMORE!! WIRED UP FOR 120 VAC BUT CAN BE EASILY SWITCHED OVER. It got me about 1200+ watts on a 120 VAC supply. I was not trying to push it either.... If you want more (nobody would hear the extra 300 Watts anyways) you should really convert and connect it to a 220 outlet.
