This document is a Single Source Justification (Simplified Acquisition) for the procurement of Low-Noise Voltage Pre-Amplifiers by the Air Force Research Laboratory (AFRL/RIKO) located in Rome, NY. The government intends to negotiate a sole-source fixed-price contract with Krohn-Hite Corporation, citing the end users' extensive training and experience with Krohn-Hite branded pre-amplifiers in past superconducting circuit applications. The total estimated contract value is redacted, but the procurement is for pre-amplifiers that can be efficiently integrated into existing cryostats with minimal additional training required.

The justification emphasizes that Krohn-Hite Corporation does not maintain a network of domestic resellers, making them the sole-source provider. A Notice of Proposed Contract Action was posted on the SAM.gov site between 11 June 2025 and 26 June 2025, with no responses received indicating alternative sources capable of fulfilling the requirement. The contracting officer has determined that only a single source is reasonably available under FAR 13.106-1(b)(1). The end user will continue to monitor the market to identify opportunities for maximizing competition in potential future requirements.
