AA 32B-S

The S-Series tubes are based on an extra large size plate system. This system is derived from earlier 52B type tubes, and has proven to be most reliable for high power applications. The advantage of the AA 32B-S is the higher filament current, which will make it possible to reproduce peak-power signals with less distortion.
