from vacuum
tubes still in use today like the 6L6 I think I saw
mentioned recently to picture tubes (even a few colour types) to
tube types I've never heard of like "nuvistor" and "novar".
Well, it's good that you found this, so now you'll know what they
are.
Well, not really. There were some cutaway drawings of nuvistors; as
near as I can figure, they're just ordinary vacuum tubes except made
with metal rather than glass shells, and with somewhat more
mechanically sturdy element mountings. Novars I still don't know
anything significant about besides the numbers in the table.
If you really want to see a comprehensive RCA tube
manual, check out
the ten volume, (nearly) 7,000 page, RCA HB-3 which includes
everything from ingitrons to transmitting tubes. :-) It's presently
available on CD for about US$80 from Antique Electronic Supply.
One of the products advertised in the book I have is a five-binder set
which "contains over 5000 pages of loose-leaf data and curves on RCA
receiving tubes, ...". Price "$20.00 including service for first
year", but without specifying what "service" is included.
And it's called the HB-3. :-)
