Wunder Audio CM12 S

Tube

The Wunder Audio CM12 S tubes are hand tested NOS GE 5-star 6072A:

• 6.3 volts DC filament voltage,
• 120 volts DC plate voltage

The GE 5 Star 6072A is one of the finest 6072 tubes ever made. In fact, the GE 5 Star 6072A’s are the only 6072 (12AY7 variant) tubes recommended in high-end applications. The primary special purpose of a 6072 is its super low noise and microphonics. That is why these tubes are important in microphones and first stages of high-end audio equipment. These special purpose dual triode tubes are equipped with spiral wound heater filaments to eliminate hum and have to pass rigorous screening for noise levels.
