maximum and minimum voltages the amplifier can go to. Whether it's
single ended or double ended (one transistor, or two doing push
pull), and what the supply DC voltage is will determine this. Of
course, by the time you get to the 'rails' you've really distorted
your signal...but that's good, to me. Many amplifiers are more
efficient and distort the least with lower outputs. I like to turn
things up to eleven though. But not for guitars. Look at what your
DC supply voltage is, and that's probably the peak to peak output
voltage of the amplifier, though it can be less than that depending
on the circuit. In fact, it probably will be.
But I may have no idea what I'm talking about.
- I didn't see an answer to this. But, mail has been slow through my
server today. so forgive me if this is a repeat. "Rails" is a term
that refers to the power supply voltage, often times on a bipolar
power supply. So, if you have a typical power supply designed for op
amps and such, it might supply +15 VDC and -15 VDC. Some might
include +5 VDC is there are logic circuits. These power supply
points are often called the "rails."
