 First I have been informed that some of the better
designs for tube amps were originally published by Mullard and
Williamson.  I have also been informed that these designs are in the
public domain, but thus far through the engineering library here, have
only been ablle to find an ultralinear design by Williamson.  I would
like, however, to do this design in triode and in a class a.  I don't
know if these original designs are single ended or push pull.  I assume
the latter.  Anyway, if someone could direct me to either of these
designs or another tube design that people feel is high in quality I would

would appreciate it.  Second question is where is the best place to get
parts for this project.  Is sonic frontiers it?  What other sources are
there for high quality transformers and other parts?
