Bob, Yes, thank you. I see that I concluded that it doesn't have sections 8 and 9 because I was looking at the end of the PDF, which are the Change Information pages. I do see the duplicate

Hi Wamor, As far as I see the IDs on my boards, in my table, and your ID, the ID refers to something else. TDS520,TDS540,TDS620 use the same ID. Sorry to be encouraging. Maybe, H?kan is right. The

The copy I look at came from this link: https://w140.com/tekwiki/images/0/0a/070-5880-00.pdf Part No. 070-5880-00 MANUAL Product Group No. 42 First Printing May 1986 It has what I assume is section

I don't see any duplicate pages in the TekWiki copy of the 7934 manual. Also, the May 1986 PDF ends with section 7. My copy (Aug 1987) has sections 8 and 9. I'm a bit confused. It would be helpful

Could you send to me the logical PDF page numbers of the pages to which you refer? Thanks. DaveD KC0WJN [email protected]> wrote:

I forgot to mention but I also noticed that there appears to be duplicate pages 6-16 to 6-20 and 7-18 to 7-21 at the rear of the manual. I did not compare them to see if there was any

Dang. I forgot to write that I also added the missing page 3-1 to the May 1986 revision. DaveD KC0WJN

All, Ok, I've unbound my 7934 manual and I started scanning the missing pages. It turns out that my manual copy is Revision May 1986, but *Revised Aug 1987*. Per Bob's email below: Pages x, 9-12

It's on Tekwiki, at least it is there now. -- Roy Thistle

Andy, By your video, the high voltage condensers are ceramic. It is possible/likely one or more of the 5W blue resistors will be open. I have seen these open in 500 series before due to being run

Thank you. Sigh. I guess I'll have to unbind my copy and add those to the copy on TekWiki. DaveD KC0WJN [email protected]> wrote:

Looking through the manual, of the pages with numbers, the following are missing: X, 3-1, 6-22, 6-23, 7-61, 9-12, 9-24 Bob

It occurs to me that, if I am going to unbind my 7934 manual (re-binding is a pain) to scan pages 6-22 and 6-23 in order to update the copy on TekWiki, it would be useful to know if there are any

"In the hv section, see if the .01mfd condensers are ceramic or tubular" Are the ones you refer to high voltage types IE 1KV +? Yesterday I pulled the CRT in order to clean the X & Y plates

I should probably update the PDF of the manual on the TekWiki site. That'll take a bit longer. DaveD KC0WJN [email protected]> wrote:

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

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
