[CambridgeWorks]

Hi Peter, for old times sake I wish I could help but am certain all my manuals went about 10 years ago, just keeping a few of very rare ones. I will look just in case. Btw it is 50 years since we worked in Cambridge!
As Jon says, the lid fitting is critical as helical resonators are contained within. A fibre tip burnishing brush was a handy tool to polish up the mating surfaces.
In service I found the T30fm the most reliable gear of that era. Fit and forget, unlike the AM tx, frequent replacement of QQV03-10.
Basic R17 alignment is same as W15fm, the R18 only has the selective front end as a difference afaik. The cascode fets sometimes failed with near lightning strikes.
Before any alignment, dribble some ipa or similar in the coils to free up the slugs. NOT the beer IPA or even "Dark Tolly and Mild" from 1968!
