Hi John,
Can't track it down from any of the usual places, but Mauritron do list two other SE Labs scope manuals, specifically:
SE Labs EM-102 Oscilloscope Instructions covers both Operating Guide & Circuits Schematics Service Manual CDC-673.
SE Labs SM-111 Oscilloscope Instructions covers both Operating Guide & Circuits Schematics Service Manual CDC-673.
It may be that the SE112 is totally different from the 111, but it could be that it's a further development of it, so who knows - that manual might be of some use.
You can download manuals from Mauritron for £10.00, and it might be worth phoning them or dropping them an e-mail enqury to see if they can source the 112 manual, of give any advice on it.
01964 533239 or 07931 771954

There's some info about SE Labs at this link, which you may already have found, but which though interesting, isn't of any help:
http://www.radiomuseum.org/dsp_herstelle...y_id=12221
I think the scope dates from 1972 or thereabouts, and was one of the first to use transistors rather than valves, thus, most of the circuitry will be low voltage except of course the EHT. For something of that age, apart from transistors becoming suspect, electrolytics may well have dried out and developed a high ESR, which you can test with them in circuit with an ESR meter with the scope switched off and unplugged, but of course you need to isolate that to the part of the circuit that you think might be suspect, or it just becomes a fruitless guessing game.
Sorry I can't be more helpful.
Best of luck,
David
