Ok so chipamps are not really my thing but I just saw a post on a tda 2030 amp....
Doesn't time mean progress for integrated electronics? This is a chip amp from more than 20 years ago !!
So that got me thinking
What's the history of this ilittle pentawatt ?
Is it surviving still because of momentum or because theese devices have actually got some nice features? If so what are they ?
I recall building some off Thomson datasheets in my youth and they sucked then. So I'm a little surprised they are stil around.

Yes, I did them too . Normal, bridge and superbridge !
But to take the full picture, you should describe also the rest of the system...
'cos nothing plays alone.
Well I guess I had better hf hearing then.
And maybe more testosterone.
And 3-head tape decks.
And some unmemorable Japanese 3 way spekaers that had treble control pot on the front.
I had 2N3055 based ap then that sounded nice even with the handicaps above. The 2030 chipamp.. Well let's just say that it was a special kind of sound that may have suited a special kid of person. Too bad that didn't include me,, caveat though I did not have scopes or analyzers then other than the aural kind .....

The GENIUS who invented the TO220 5 pin power amp was Milan based ST Engineer Bruno Murari.
All others are evolution or copies (sorry, "reverse engineering"
) of his designs.
Like most great men, he's too modest, so his story is told by others, even his competitors:
