calling randal, john, OTM, and others:
hi guys, giving a presentation as part of a job interview process (i was
able to choose any topic as long as it's "technical") and I'm hoping
someone has succinct answers or links to answer some of the
foolwing.
1). it is said that one reason why tubes sound "better" than transistors
is because they clip softly. why would a tube amp clip more softly than
a SS amp?
2) it is said that tube amps sound "better" because they generate even-
order rather than odd-order harmonics (when distorting). I could see
how this would be related to the above, but it seems it could also be a
mechansim of most tube circuits using minimal feedback (as feedback
lowers the amplitude of distortion spectrum, but drqaws it out in terms
of more and more harmonics...)
3) what accounts for the greater effeciency off PP topologies besides
the fact taht you can run them in class a/ab, ab, or b, and that the
power supply requirements are easier as there is complementarity
between the two sides?
any help appreciated. need to finish writing this tomorrow (Tues) for a
wednesday presentation. thanks
