Opis oglasa
031337262
Country:
Great Britain (UK)
Brand: Mazda = Valve (Tube) brand GB (see also France)
Tube type: Transmitting Tube, Pentode, air cooled Power/Output
Identical to ATP4 = ZA5502 = V248A = CV1366
Base Octal-8 GB, (Mazda), K8B, MO (Codex=Vr) Top contact with a cap.
Was used by Military and/or Government
Filament Vf 2.3 Volts / If 0.34 Ampere / Direct / Battery =
Description
Heater ratings: Vf- = 2,3 V; If = 0,34 A
Vf-min = 2,0 V; If-min = 0,3 A
Vf-max: 2,6 V; If-max = 0,37 A
Va = Vg2 = 150 V,
Ia = 38 mA
Vg1 = -8V,
Ig2 = 10 mA
S = 3,6 mA/V,
Pa = 5 W
Contains 2 pentode units strapped in parallel.
The data sheet: „Specification MOS/CV1366/ Issue 6, dated 2.9.1946 by Ministry of supply (S.R.D.E.)“ calls 2.6 V as heater voltage, which has to be regarded as the maximum value.
However, the heater current 0.3 A, as mentioned there, corresponds to the minimum voltage 2.0V.
By investigations on real circuits, a heater voltage of about 2.3 V was found out.
Imam kar nekaj stare / nove elektronike, drugih starin, prašnih dobrin :-)
Preglejte če bo kaj zanimivega za vas.
