Thanks Barrie, that's just the info I was looking for.
Not too far into the transmitting volume I find the 4-65, which has 5 pages.
(Built a push-pull pair of these for 6M in the middle 1950s)
Next is the 4-125A, with 3 pages.
Next is the 4-250A, with 3 pages.
Next is the 4-400A, with one page.
Then comes the 4X500A, followed by the 4-1000A, which has three pages.
I have five volumes of the HB-3. I have this particular book out at the
moment because I've been helping a local ham with a 160M 813 project.
73, Barrie, W7ALW
