The '''157-0039-00''' denotes a matched pair of [[6AW8]](A) ([[154-0095-00]]) tubes. The matching involves only the pentode secion of the tubes. | |||
==Matching Conditions== | |||
*Heater: Nominal | |||
*Plate voltage: 120 V | |||
*Screen voltage: 107 V | |||
*Cathode current: 12.5 mA | |||
==Selection Requirements== | |||
A: Cathode bias of two tubes of a pair shall be within 50 mV. | |||
B: Cathode bias must fall within 1.35 − 2.9 V | |||
==Selected part use== | |||
*[[541]] (V1025 & V1040 / serial nr. 101-6474) | |||
*[[545]] (V1025 & V1040 / serial nr. 101-9291) | |||
