Digital Amplifiers don't sound like Transistor or Tube driven Linear Power Amplifiers.
Hand-built tube amplifiers for guitar and harp.
In amplifiers, a small current applied to a tube or transistor to reduce crossover distortion.

Output transformers are usually essential in tube amps but are almost never employed in transistor amplifiers.
Travelling wave tube amplifiers (TWTA) have bandwidths of 500 MHz and more and powers from a few watts to many kilowatts.

Valve Amplifiers by Morgan Jones Valve amplifier or tube amplifier are considered by many to offer better quality sound than transistor amplifiers.
Originally amplifiers employed vacuum tubes to boost the analog signal to an amplitude (voltage) that could move a loudspeaker cone.
Today this design is seen only in glass tubes used in audio amplifiers, not in ceramic power tubes.

Advent also offers travelling wave tube and klystron amplifiers suitable for a whole range of amplifier power applications for fixed, mobile and flyaway systems.
All Spectron amplifiers are digital Class D - the next step beyond conventional transistors and tube systems.

Parasitic oscillations are by no means uncommon in power amplifiers, and there is reason to believe that tube design is a factor in their incidence.
