*Maybe* because it's google.UK and you are checking it from "inside" GB?

@kuurna (you aren't a Space Alien for which "Earth should stand still", are you?): post a couple gut pictures showing chassis and cabinet inside, *maybe" you can fit a power amp and PSU inside the *cabinet* section, leaving everything else as-is, using just the old preamp.
Driving the new 10", of course.

I suspect the limiter will stop working though.
Very odd???

Fine.

I would make a nice 10/20mm hole in the bottom of that chassis so as to pass 220V and signal cables to the lower side, where the speaker lives, and mount on the bottom of the enclosure an LM3886 power amp and its power supply, so turning the original amp ON will turn both ON at the same time.

The upper one can work without a speaker connected and the bottom one drives the new speaker.
