I have come across one of these superb pre power combos .
They are +- 24 v split rail pre with Ferranti e line transistors .
Even bias presets on the pre amp boards apart from the buffer .
It has suffered leaky capacitors at one time .
The power amp is quasi complementary largely class b with T03 i
Output devices .
A huge Holden fisher toroidal transformer in the amp .
I’m currently drawing the schematics if anyone is interested .

It might not be of interest now.
But I am sure that at some stage in the future someone will be thanking you for the information.
I would also suggest that you upload pics and schematics to the servers here to safe guard them from disappearing in the future 🙂

They are looking very interesting, thanks for drawing the schematics for repair and studying.
