NOTES:
1. See "Reduced pressure (altitude) rating", and altitude, maximum peak voltage in the basic document.
2. This test to be performed at the conclusion of the holding period.
3. Ebb = Ecc2 = 135 V dc; Ec1 = 0; Rg1 = 3.3 Meg; Rp = 0.27 Meg; Rg2 = 2 Meg (by-passed with a 0.5 µF capacitor
to -f). Remove tube and adjust gain of amplifier for 50 mW output with Esig = 3.0 V ac.
