Application Notes
The 82 is designed to supply d-c power of uniform voltage to receivers with varying current requirements. It requires small radio-frequency chokes (1 mH or more) in series with each plate lead to eliminate impact excitation noise. For half-wave operation with plates in parallel, use a 100 Ohm resistor in series with each plate.
