The super tubes!
Exterm long life is to be expected, presumably up to 20k hours are realistic, we are told by owners of the predecessor types,
1 year warranty when used correctly!
The S-Series tubes are based on an extra large size plate system. 52B type tubes, and have proven to be highly 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.
