[Amps] I'm not kidding: TL922

[Dave Borcher]

Group, this is for real, I'm looking for suggestions.  TL922 amp, fairly
good condition;when I key it full power for tuneup or CW, my little dog
goes absolutely nuts.  An LK500 amp doesn't bother the dog.  I like the
TL922 but I don't like to torment the dog.  I suspect transformer
laminations buzzing, but I'd have thought I'd hear that.  Again, this is
for real, and I'd like to hear serious suggestions of what to look for or
how to test.  Thanks
