ECC99
R. F. DOUBLE TRIODE Base: NOVAL
Uf = 6,3 or 12,6 V If = 800 or 400 mA
Typical
characteristic: Ua = 150 V Ug = -4 V Ia = 18 mA S = 9,5 mA/V Ri = 2,3 kΩ µ = 22
Limiting values: Ua = 400 V Ik = 60 mA
Uk/f = 200 V Wa = 5 W
Capacitances:
system I. system II.
cg/k = 5,8
5,8 pF
ca = 0,91
0,81 pF
cg/a = 5,1
5,1 pF
Recommanded use: Driver of power triodes such as 300 B, 2A3..., Output stage headphone amplifiers, preamplifiers, power stage little P-P triode amplifiers (10W4xECC99) and parallel voltage power supplies. Can be used instead of 5687, E182CC, 6840, 6BL7. Note: Outlets on some of these types, could have different set-up.
