Well, the Apache will send SSB, which is a good feature to have, whereas
the DX-100 won't. On the other hand, the DX-100 is much simpler, as a result.

But I would pick whichever of the two is factory-wired. If they were both
built as kits, I'd pick the one that has the best-looking solder joints.

Good advice but if the rig is primarily for AM I would
check the manuals to see how its generated. The DX-100 is
plate modulated but most SSB rigs do AM by either injecting
carrier on one sideband or with controlled carrier or some
other scheme that will work with a linear amplifier.

Disregard my post. The Apache does have plate modulation,
I was confusing it with another transmitter.

But it was a valid point to check. Most SSB transmitters used low level
modulation for AM, so the Apache then becomes a relatively uncommon item,
an SSB rig that does plate modulation for AM. That tends to make it a
better choice, since it does SSB too.

Let me guess: this approach gives you higher output power on AM since the
final can be operated class C, but it doubles the weight of the transmitter
with that huge modulation transformer?

So, you're saying "win-win!"?

The Apache by itself does not have SSB capability. For that, you also
need the SB-10 Sideband Adapter. I had both but sold them years ago.
