I get asked about this fairly often, there are a number of different ways of measuring the voltages
so here in one place is all the amps i know about, and all are rated the same. The voltage is
peak to peak voltage measured from one stator to the other stator.
For solid state amplifiers, the output voltage is usually very close to the power supply rails.
For OTL tube amplifiers, the Rp of the output tube(s) usually takes about 60 volts off of the
maximum voltage swing, for Stax made amplifiers the negative power supply is increased to
compensate for this. These are theoretical maximums, in practice the voltage swing will be less.
There is of course more to these amplifiers than just the voltage ratings, Slew rate into a
capactive load is also very important, i will be measuring some of these amplifiers and will
add slew rate at a later time.
