Application Notes
The 32HQ7 is a multifunction compactron containing a high-perveance diode and a beam power pentode. The diode is intended for service as the damping diode and the pentode as the horizontal-deflection amplifier in television receivers. The diffusion bonded cathode practically eliminates back-emission from the anode.
