[Amps] 3-1000 Amplifiers

[Richard Solomon]

A local found a BTI LK-2000 in an SK's barn (really, a true "barn
find"). That got me wondering
how many Ham Amps were available (commercial not HB) that used the
3-1000. I guess that
the proliferation of 4-1000's may have limited the 3-1000 appeal.
The LK-2000 I saw was only the second one I have seen in 55 years of Hamming.

Does anyone know of any other commercial Ham Amps that used the 3-1000 ?
