Deflection circuit: fvert = 50 Hz; tFB = 640 µs; II(bias) = 400 µA; Ii(dif)(peak) = 290 µA; Io(p-p) = 2.4 A.
East-west amplifier: Ii(B) = 290 µA; Ii(T) = 510 µA.
(1) Optional, component values depend on the deflection coil impedance.
(2) Extended flash over protection; BYD33D or equivalent.
(3) Optional, extended flash over protection.
