what would be a modern, reliable equivalent for a voltage stabiliser?

There you go, presuming you mean the one for the clocks.

As Shooters post but the capacitors and diode, while a good addition, are not needed. Just a 10v regulator will do fine on its own.

I was going to fit it on its own but while chatting to my amp man he said " no we can do better than that" a quick Google later and he pinged me the diagram over, he did tell me why its better but me being an electronics div it went straight over my head, hence why I have a man who repairs my Marshalls.

Yes but given the crude nature of the gauges they are not needed.
Electrical and electronics are my trade.

Many people have used the LM7810 without them for this purpose without issue. The capacitors are mostly used to smooth out the output signal. Your "amp man" is used to audio equipment where the output needs to be nice and smooth. The factory stabiliser just pulses the signal to average out to 10v. The LM7810 is far smoother just by itself.

Also the capacitors and diode won't realistically fit in the original stabiliser casing so you would have to find a way to mount it all.

I definitely remember the word smoothing then my brain went into humming mode, he did ask if I had an old case as he said he can fit the gubbins ( my word ) in on a small board, I told him not to bother as it's a git to get to, so he's going to put it in a small box so I can bolt it where I like. Sounds like I'm on a win win any which way it comes, and all at my favourite price to boot.

The capacitors are added here to act as a poor man's voltage spike suppressor. When large accessories (eg driving lights, high beam etc) are switch, there's usually a higher voltage spike from the alternator.

For the cost of them and what they may do, I always add them in
