20 Meter SSB Transceiver?

One of the common things back then was seperate TX and RX.
Though some would build a single band Trasnciever and use it
with a Transveter to cover other bands.
Yes, it was more common to see separates. ON the other hand, when
there were actual transceivers described, they did tend to use
common circuitry between transmit and receive. Solid state, because
of their size and low cost, has made it pretty easy to build
complete separates (minus the oscillators) in one box, which of
course does have the advantage of making switching pretty easy.
One advantage of separates is that it looks less daunting. Build
the receiver, and you have something finished, and even have it
for testing the transmitter. Then build the transmitter. The
overall product may require more work, but at least it's broken
down into more manageable pieces.
Othere QST articles QST April 1961, A 75M SSB tranceiver.
I'd bet back issue reprints of QST articles are available from ARRL..
Traditionally, and I'm not sure why it would have changed, you could
get back issues for a reasonable fee, and if they didn't have any
of that issue, the specific article for a reasonable fee.
Of course, one can also get back issues on CDROM, and for someone
interested in the tube era, it might make sense to get a set from
the era when tubes were still pretty common in QST, but late enough
that things had developed well.
Old Handbooks of course not only have the construction articles, but
the peripheral information that might be needed by someone starting
to build tube equipment at this point. That 75metre SSB transceiver
that you mention, it showed up in a number of Handbooks in the early
seventies, and yes, it sure looked neat for an 11 year with his
first Handbook in 1971.
