Overview
The Heathkit 831801 relay is a general-purpose switching relay engineered for use in Heathkit SB-200 and SB-201 linear amplifiers. The Heathkit SB-200 was introduced in 1964, and the SB-201 was introduced in 1978 without 10-meter capability due to FCC regulations. This relay serves as a critical component for antenna relay circuits and RF switching applications in these classic HF amplifier systems. The Heathkit 831801 is a new, no-box condition part ideal for restoration, repair, or maintenance of vintage Heathkit amplifiers.
