Al, I faced a similar dilemma with an R1155 that I started 3 months ago.
I do prefer the one bit at a time approach that Mark has suggested but the trouble with British comms receivers is that they were usually ( at least ww2) handwired point to point with very little modularity in the build. Moreover being comms receivers there is a lot to them.
For me with the R1155 the wiring was absolutely perished and as such the decision was made for me to completely strip the whole unit down. This then leads you onto having to consider to clean and respray panels etc while the whole thing is stripped down and do a full restore (while you have taken the trouble to strip down).
It grows like "topsy" as you know so unless you really want to get into a full restore I would rewire stage by stage, I would isolate unchecked stages from the HT point of view in case there is something untoward and just steadily work away stage by stage. ( As you can see I am making slow process with the R1155 and am at the stage where I am thinking what have I let my self in for
)
It certainly would make a very interesting success story when you have done it especially if you could do lots of photos' for the gallery. I have never owned one of these sets but from what I can gather performance wise they are a bit of "a wolf in sheep's clothing" I believe they used them at Bletchley Park so they must have been good.
I must say I would rather restore an R1155 than a CR100 at least the R1155 chassis is as light as a feather and very easy to hold in a puropose made jig , I suspect the CR100 is the usual heavy weight being a naval receiver.
Good Luck
Mike
