Besides old ARRL Handbooks prior to the 1970s, I'd suggest
finding the site that has digitized copies of GE Ham News.
Those were (bi-monthly?) hand-outs by GE to push their
tubes (naturally) but they contained lots of different ham
projects (using tubes, of course).

Got it! Thanks a lot Len - I googled them up, and have enough reading
material to keep me busy for a while.

the site is: http://bama.sbc.edu/ge_ham_news.htm
