Well I need to correct my own post.
(sri)
The Triton I was the 510 and had 50w out.
The Triton II was the 520 and identical to the 510, except it 100w out.
They both also had 4-pole xtal lattice filters, like the Argonauts.
AND they both also had the 4-kHz tuning rate on 10m like the Argonauts.
The Triton IV 540 was analog, the 544 was digital. Otherwise they were
identical.
They had the 8-pole filter, 4x 500 Hz band segments on 10m and it was the
10m band which was hotter.
I think I have it correct now.

ABSOLUTELY NOT!
The receivers in the 505 and 509 were basically identical and very similar
to the Triton, but the Triton had switchable crystals for the 10m band,
giving coverage in separate 500 Hz segments. It also had an 8-Pole crystal
lattice filter, whereas the two Argonauts had only 4-pole filters. The two
first Argonauts changed the rate of tune for the VFO on 10m, so each mark on
the dial represented 4 kHz instead of 1 kHz. They were not great 10m rigs.
I found them a bit difficult to tune on 10m.
When the Triton IV came out, it had a hotter receiver than the original
Triton. At least that is what I was told by the engineer that designed it.
It also had an 8-pole xtal lattice filter. I don't remember what they
changed but it was supposed to be better than the original Triton.
When the Argonaut 515 came out, it got the Triton IV receiver, except it
also had only a 4-pole xtal filter in it. At least it had the switchable
10m band segments.
The biggest difference between the Argonauts were, the 509 had a broadband
TX driver, whereas the 505 had a tunable driver. The tune was controlled by
the little elevator that went up and down to tune the RX stages. The SSB
generator board was updated on the 509 but I can't recall what the changes
were.
The 515 got the Triton IV RX and the 4 switchable band segments on 10m. It
also got slightly larger knobs for most controls. Finally, it got a new
paint job, making it look more like a real radio than a plastic toy! ;=)

Owning a Triton IV, wasn't the receiver essentially same from Argonaut 509
through all the Tritons?
