Rectifier - TV Line Scan Boost ·Rectifier
High-voltage television flyback/EHT rectifier electrically related to DY86, with treated envelope for demanding environmental conditions. It converts horizontal-output pulses into the CRT accelerating-voltage supply.
High-voltage half-wave rectifier electrically identical to DY86, with treated envelope for high-humidity and low-pressure operation.
Small-button Noval 9-contact
