Good afternoon All
Rupert, I think you are likely our only option to get hold of the missing pages. 2 other group members sent me really good copies of Part II after my request, just before Christmas, and both are missing the elusive Chapter 25
I am going to write to Colin Hinson (RAF Museum ex Hendon) but could be a long job as I know he has a backlog of stuff to archive.
I will be be happy to pay the? bill from the Copy Shop if you are able to get the pages scanned.?
As per prev post in the absence of a parts list, I foolishly guessed that the 1778 displays were same as the 1772 I don't have a 1772 so now looking for a use for them!!
For the time being, I'm up to date with the 1778's but I am going to be more careful in future!
I had some corroded wiring, mainly on the terminations of screened leads onto the IF boards,? which I thought might be caused by acidic flux. It was a real mess - the braid had more or less disintegrated. I managed to cut and re terminate but only just. When I was a broadcast engineer we used a lot of Hellerman sleeving and the Hellerine lubricant. I don't remember any problems even on old stuff so I think there must be some other treatment involved? The other mechanical issue was the foam rubber padding strips which had fallen to pieces! I'm still looking for some suitable material.
1792
I have a similar problem with schematics for the 1792.
Dan, I know you have a lot of experience with the 1792/6790 but so as not to complicate this thread, I'll write a separate note with all the details.
Essentially all the manuals I can find have got either parts of schematics missing or v poor definition.
I'm getting on quite well with my repairs but starting to get sore eyes after gazing at a really bad copy of the main IF board
