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.
