SVETLANA TECHNICAL DATA
6D22S
High Performance Half-Wave Rectifier
T he SvetlanaTM 6D22S is a glass-envelope power diode for use as a half-wave 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.
