The odd 24V psu in the main PSU box is for the chimney fan cooling the 4700uF caps in the main amp.
If you count the umbilical as an R, we end up with CLCCRC.
22000uF / 2.2mF / 22000uF / 22000uF / R / 4700uF

I have to admit if it was my build, I would wire it slightly differently.
I would remove the copper pipe 0V link and move it to the third (o/p) bank.
First two caps, remove the 0V link, add a new link from the first to the second cap bank in parallel to the other 0V wire closest to the transformer; you could think of it as two separate single supplies joined at the output.

Itsmee, I'm in tune with your line of thought and tend to agree.
I'm wondering how much affect the umbilical will have?
Each PSU connection, +/0/- is connected via 3 x 0.75mm cores, 9 cores in total for each channel. 18 cores in total for L + R

Well, I finally got around to putting the new build together. I did follow Itsmee's advice and re-route the capacitor cabling.
I was impressed, the amplifier is silent without any further caps in the main enclosure.

Congrats on getting back up and running! I suspect your new PSU will outlast the old one by quite a bit of time!
