[snip amp details]


The IM and THD charts that come with the manual are blank
and marked "Disclosure prohibited 4.11.1974"


I must confess I burst out laughing when I read that! Did they think the
detailed distortion performance of their amp was a 'trade secret' and
that no-one should be allowed either to know the spec or measure it for
themselves?!


Possibly because the results were so bad?


You snipped the figures I gave. They are excellent.


z The Crown amp was loved by the
pop boys because it was loud and brash. But when used at normal levels for
GP stuff, bettered by many others.


The Crown amp was popular everywhere, it had the power to be loud
but not brash. Driving large Tannoys or Lockwoods it made a very
impressive monitor system. A good vinyl cutting amp also.
