Chuckle well a lot of the problem with Sinclair was that his designs fine
but when they made them they stopped at nothing to source the cheapest bits
they could to the detriment of the actual performance.
The IC amps were even worse. The IC10, was basically a power op amp with no
protection against self destruction.
The IC12, was I believe a Texas Instruments design, again with no
protection and far too much gain close to the high power parts which meant
that any supply issues were fed back to the input making it sound very bad.

The only bit of his bolt together hi fi that did work quite well was the
stereo decoder for the fm crap tuner.
I did put that on aan old tuner I had after removing the de emphasis and it
sounded very nice and low his levels, but then there was not much inside it
an a single chip was there?

it was not bad for crossover, it did sound kind of fluffy at times.

This one? http://rk.nvg.ntnu.no/sinclair/audio/z12.htm
What a pile of crap!

I became quite adept at fixing Z30s in my youth.

Maybe a much bigger heat sink would have helped
but they hardly ever survived a party.
