GEC / OSRAM 921 console score

[FlaCharlie]

Will do - they are a pair (I assume) of multicap cans with 8uf / 16uf @ 450v in each. I'm going to wire in 10uf / 20uf replacements rated at 500v as I simply cannot get the multicaps anywhere in NZ. I hope the slight increase in capacitance isn't a big deal (and I suppose with tolerance at 10% or so, it should be fine). I really need to find a nice full range driver for the speaker cabinet now.....

That's a beauty!

Using a 10uf first cap should be fine but don't go any higher. The data sheet for the rectifier specifies 8uf but the circuit doesn't seem to be drawing as much current as is allowed, so you should be fine.

Is the metal coned speaker missing from the cabinet?

tolerances being what they are you should be fine. The old ones were often something like -20 / +80. Broad side of a barn essentially.

Sadly yes, although there are the letters EV stamped inside the cabinet which may suggest an Electro Voice driver was in there at some point perhaps.

I love how some old gear is just "oh hey, lets put all the high voltage stuff right on top with no cover. What could go wrong?"

That is my thought exactly
What a surprise if you reach inside the cabinet while it's on. That always bothered me about many of the European transformers. Grundig radios come to mind also. Many of the early US made TV's also.
