Vintage tube ABC1 – Triode and double diode.
Lamps from old Hungary, unused, working and measured – original NOS. Gold series in original box.
Checking measurements were made before the lamps was put up for sale.
Triode part: Ua = 250 V and Us = – 6 V, the emission was Ia = 7.02 mA;
The so-called unused NOS in such conditions. measurement is Ia = 6.8 mA
The diode part of the lamps at 12 V: d1 = 1.012 mA and d2 = 1.014 mA
The lamps has catalog parameter values.
The photos show the lamps for sale, the so-called Real-Photo, comes from my private collection of lamps.
