Triode section; electrical data otherwise same as EABC80 per source. HABC80 triple-diode triode for AM/FM demodulation and AF amplification. Lorenz states that electrical ratings and characteristic curves are the same as EABC80 except for its 19 V, 150 mA series heater. Triode typical gm 1.45 mA/V, mu 70, rp 48 kΩ; published maxima include plate 300 V, dissipation 1 W and cathode current 5 mA.

Diode
No fixed ratings are recorded for this section.
Diode section 1. Physical diode 1 of the Lorenz HABC80 triple-diode triode for AM/FM detector service. The manufacturer identifies equivalence to EABC80 other than heating, but specific distinct diode limiting values are held pending confirmation of the diode-to-section assignment.
Section 3
Diode
No fixed ratings are recorded for this section.
Diode section 2. Physical diode 2 of the Lorenz HABC80 triple-diode triode for AM/FM detector service. Distinct numerical diode maximum ratings are not promoted pending confirmation of diode-to-section assignment.
Section 4
Diode
No fixed ratings are recorded for this section.
Diode section 3. Physical diode 3 of the Lorenz HABC80 triple-diode triode for AM/FM detector service. Distinct numerical diode maximum ratings are not promoted pending confirmation of diode-to-section assignment.
