Heathkit Linear Amplifier SB-200 Please read description
Up for your consideration is a Heathkit SB-200 linear amplifier. I have checked it out and it seems to be in good working condition. Cosmetics are excellent considering its age and it appears to be 100% original and its clean inside and out. It's a clean one inside. The only thing I'm not sure about are the condition of the 572B tubes, the amp is putting out around 500 watts in SSB mode. I think that's just fine. The meter lights up and the amp tunes up as it should and I get correct readings on all the mode switch positions except relative power, in that position I don't get a reading. HV = 2500vdc with no load - All bands work and produce output, 80-40-20-15-10. This is a great little amplifier and is in great condition for a vintage piece of ham gear. This SB-200 is in great cosmetic and mechanical shape. I do see that one rear foot is not screwed in correctly, as the grommet is missing, but the foot is attached. The meter is faded a little and foggy.
Includes original assembly manual from Heathkit. What you don't often see is a video of stuff working... Here's the amp working on 20M with a CQ and a contact from NY to NE...
Thanks KA0BOJ ; for the contact. SK-201 Soft Key circuit installed. Harbach Electronics SK-201 Soft-Key Keying Interface. The SK-201 safely acts as an amplifier interface to your modern transceiver to the Heathkit SB-200 or SB-201.This unit is mounted inside the amplifier and transforms the negative 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.
