Does anyone know of a multimode detector IC that will handle SSB, AM
and
FM?
Looking at an old ARRL handbook I can see LM373. Is there a more
modern chip?

You can do all those modes with a DSP. 8-)

How many 12AU7's do I need to make that? ;-p

Well, you wouldn't be using 12AU7's.

At the very least, you'd be using Compactrons to get maximum tube
count per envelope.

But likely, Nuvistors or sub-miniature tubes would be the only way
to do it, if it could be done, since they are so much smaller.

I'd suggest you to try the universal and easy to solder detector - 6H6
and let the software compensate for the missed electronic skills
