Class H is a best way to make amplifiers DiY or Pro becouse have small termal disipation and is not to complicated.
Unfortunately for DiY I do not saw a simple amplifier schematic .
Only schematic wich I know I found in TDA7294 data sheet but is a little bit complex.

Maybe some other member of this forum will help us .

There was also a series of articles in Electronics World by D. Self, where he showed a worked-out example.


Another source for a class G amp is the following patent by Bob Carver (also including his strange PSU topology):

And the following one with his tracking power converter (even the prior art is interesting):
