The 2A3 is an audio power triode that is still used in amplifier designs. Modern manufacture reproduces this directly heated design. The 2A3 is normally used in a push-pull arrangement and care needs to be taken in the bias settings for each valve as a small change in grid bias will greatly alter the standing anode current and any mismatch will impair the reproduction quality. This example has two triode assemblies within a common anode. The sections are connected in parallel internally. This arrangement is believed to date to the s.
