Ok, so here's where we differ in the Schematics - in my Service Manual (original B&O paper, not pdf) on the transistor chart, TR17 is shown as 8320097 which shows BC107B in the metal-case format, but actually a BC119 is installed (which shows as 8320124).
If your SM matches the installed components, then you probably have an updated SM.
But anyway, I'm OK with the fact that my components onboard are identical to yours!
