I'm
in the process of building another amp. Originally I was going to build
mono blocks, so I have two of everything. Then I came a cross a cool
chassis and decided to built a stereo version. My last amp used LM3875 chips and this one uses LM3886.

You mention 'digital' in your title, I presume you meant to say class D ?

All the amps mentioned are class AB.

41hz has class T (a type of class D amplifier) amplifiers up to 300Wx2 in basic kit form. You provide the chassis and transformer, they provide the amp and power supply circuits.

The AMP10 basic kit (shown) has up to 100Wx2, and is $73 plus shipping.

In T-Class amps, I've built three Winsome Labs Mouse amps that use the Tripath controller TC2001and the ST Microelectronics ST505 power chips. It is one of my favorite amps. Everyone who
hears it is impressed with the big sound from the little box.

Here is a pic of the internals. The ST505 chips are surface mounted to the bottom side of the board.
