[Amps] IM distortion and such

[k7fm]

I recall that QST had an article on a 2 tube amplifier using the UE572 tube 
that was made for hams.  I think the article was about 1957 or so.  Gee, the 
years seem to melt together.  The front panel had a tear drop meter.  That 
was the first amp using that tube that I know of and they were advertised in 
73 by the manufacturer.  Might have to do some research on that one.
