What's so special about this? Other than the board on the end of the ribbon cable,it looks fairly normal ? Confused

Saw plenty of these around 20 years back, Matrix made. Not bad, nothing remarkable either.

This weekend’s project is re-capping both of these, electrolytics only naturally. The pre-amp is 28 years old, the power amp 27. Both are heavily biased into class A so run very warm. Around 110w pc at 8R.

Everything arrived from Farnell yesterday, just need to find my roll of silver solder now, as that is what these  are made with.

20 years ago would be about the correct era....

It seems to share a lot with the UKP1300 / STR1200 amps, except the daughter board the internals look like a mirrored UKP1300.
