Swan changed to the 6JH8, probably for cost reasons.

That's true, but the Swan transceivers weren't using the 7360 as a
receiving mixer. They were using it as the balanced modulator in the
transmitter section, which is a very different job, and the 6JH8 was a
low-cost alternative.

The 6JH8 could probably be used (with mods) in a lot of SSB
transmitter projects from the hollowstate era, rather than the 7360.

I've tried both, and the 7360 wins by a long way - it
probably proves
that "you get what you pay for"! �The 7360 gave me
useful conversion gain,
a spectacularly high intercept, and as low a noise figure
as you could ever
wish for.

What circuit and values did you use, Bob? Voltages, balanced vs.
unbalanced, output and input circuits, etc.?

Just looked on bay.
Wow, the 7360 is as expensive as 1L6's!
