I have been skimming this thread, since I have a 7934, but not really paying close attention to it.
I have an original 7934 manual from Tektronix, dated May 1986. It does have pages 6-22 and 6-23. I can scan and upload them or send them privately.
It'll take me a day or two to do that.

After looking at 3 totally different scans of the same printing of the
7934 manual I don't believe that pages 6-22 and 6-23 were in any
manuals from the first printing. My three scans show file sizes of:
1. 112,361 KB Title "7934 Oscilloscope (1986) WW.pdf" 464 pages
long
2. 210,637 KB Title "7934.pdf" (SECURED)
470 pages long
3. 72,903 KB Title "Tektronix-7934-service,user-ID2530.pdf" 501
pages long
#3 in the "schematics" section, the pages have been scanned 1/2 page
at a time for those pages that were probably "B"size in the original
manual. In some cases they were scanned in 1/3 page at a time.
#2 in the "schematics" section the pages are scanned the whole page at
a time.
#1 same as #2.
There are other differences in the "schematics" sections with sizes of
the pages, when I go through the pages at the same magnification
settings of the Adobe Reader. #2 has some protection applied and is
"SECURED". I can't use the "Snapshot Tool" from the "Tools" menu. In
one scan I can see the holes for the spiral binding which the others
don't have on the same page. There are other differences on the
placement of some texts. But that could be from the scanning process. I don't know.
My conclusion and best guess is that, believe it or not, Tektronix did
NOT print those missing pages in the first printing dated "May 1986". GASP!
There are pages of "CHANGE INFORMATION" in the back of each scan. One
shows signs of being stapled while others don't show this.
However is anyone can find those missing pages please scan and post them.
