I was going to post the pictures directly but to get decent readable resolution with these size pages the images were too large.
I found them in the folder of documentation for the Columbus Radio Centre test equipment. It reminds me of the courses on valve operation I did in the RNZAF - I still have all those course books behind me in my bookshelf... I should scan them sometime, but its a very thick stack of books.
Reading these 4 pages reminds me that I am a technician at best, and definitely not an electronics engineer. Just a tad too deep in the theory hole for my liking, but interesting nonetheless. I was all ok on page 1, but my eyes were watering by mid-page-2, on page 3 I skimmed and then page 4 caught my attention because I've seen this before - then spent a few minutes figuring out where - its very similar to the 75XA, 99 and 91XA output circuits.
Anyway, a curiosity that may be interesting to some...
