Notes
The 6SQ7 combines two independent diode plates and a high-mu triode (mu=100) sharing a common cathode. The diode plates are placed around the cathode, independent of the triode unit.
Triode section at Va=250V, Vg=-2V: Ia=0.9mA, gm=1100 umhos, Rp=91kΩ, mu=100. At Va=100V, Vg=-1V: Ia=0.4mA, gm=900 umhos, Rp=110kΩ.
Maximum diode current: 1.0mA continuous, minimum diode current 0.8mA at 10V applied.
