Power - Triode ·Triode
Rugged medium-mu twin power triode for high-current series-regulator and pass-tube service. Very high transconductance, low plate resistance, and roughly 30 W plate dissipation per section support powerful stabilized supplies and control applications.
Medium-mu rugged twin power triode for series-regulator/pass-tube service.
