SVETLANA TECHNICAL DATA

6D22S

High Performance

Half-W ave Rectifier

he SvetlanaTM 6D22S is a glass-envelope power diode for use as a half-wave

T

B+ rectifier in high-quality audio amplifiers. Originally intended for color­TV damper-diode service, the 6D22S is similar to the 6DL3 except for base connec­tions and some ratings. The 6D22S features very slow warmup (30 seconds
typical), making it an excellent, rugged power-on delay device for audio amplifiers.
Its warm-up time is longer than that of common rectifier tubes (such as the 5AR4/
GZ34), and it is lower in cost than electronic delay relays.
Its heater may be operated from the same supply as other tubes in amplifier,
up to Vb=600 volts. Its high pulse current capability gives sound quality which is
superior to commonly-used rectifier tubes.
