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

That is correct....................in my current version, I am using an
Analog Devices AD607 as the Sync detector, but this chip will also function
as an SSB and as an FM detector.

Does anyone know of a multimode detector IC that will handle SSB, AM

FM?
Looking at an old ARRL handbook I can see LM373. Is there a more
modern
chip?

I have some 373's and I think, some 273's as well if you'd like to try
your
hand at one. (free to good home)

It was a thread short while ago, you may also find some info on my
page http://home.online.no/~la8ak/c11.htm - unfortunately I had to PC
crashes this year so I cannot give more info, but believe Pete KE9OA
had some boards using somewhat more up-to-date solution
