- Adaptation of: EDA-01716 HPA-High Frequency PMT Amplifier BoxEDA-01716 HPA-High Frequency PMT Amplifier Box By J. Koopman 08/10/2007 Used on BWS PMT as far as I know there have not been major issues with this amplif and radiation. BE-BI-BL Jose Luis Sirvent Blasco ([email protected]) 6 2. The pCVD amplifier: A look in detail Input Protection Limited output voltage Stability and Low pass filter Relay for Test Lamp
