Representative row for three identical high-mu triodes. Uploaded sheet is reference/equivalence-only: identical to 6AK10 except heater characteristics/ratings; promoted electrical values intentionally not inferred. GE/Sylvania: three high-mu triodes for color-difference amplification; electrical ratings as 6AK10 except heater. Each section: 330 V maximum plate voltage, 2 W maximum plate dissipation; typical values at 200 V plate, 10 mA plate current: gm 7000 µmhos, µ 53, rp approximately 7500 ohms.
