Actually, the Apache used 6CA7/EL-34's as modulators. The finals were
a pair of 6146's.

This is correct. Very little difference except for cabinet design.

Just a clarification....."the B model and they used 6146s as
modulators in
place of the 1625s"....No, the DX-100B also uses 1625's as modulators.
The
Johnson Valiant uses 6146's as modulators...do not believe any
Heathkit
used
6146's as modulators.

The biggest difference in DX 100s is the use of a step cap in the
output
circuit like the Johnson Valiant used. If you have it there will be
a
step
switch to increase the values.
There was a mod kit sold to replace those caps with a variable one
and
later
versions may have the variable cap furnished with it.
That is about the only differences in DX 100s until you get into the
B
model
and they used 6146s as modulators in place of the 1625s.
Which version do you have?

I need a DX-100 manual copy. But weren't there different versions of
this
TX? Are the differences such that I need to make sure the manual I
get
matches the version I have? How do I tell which version I have?
This one also has an unoriginal knob in the center below the dial. If
anyone
has an original knob, I could use that too.
Thanks.
