Far as I know with the lm3875 and LM3886 class A-AB study classes have previously LM3886 did the difference between the two is one of the circuit between the simplicity and the other LM3886 in the bass than the one in the foreground and a strong, LM3875 the bass and other details evenly dispersed.

Circuit of the box, etc.. in components of the I did, usually amp box as use aluminum parts Soon I’d do class A amp copper for the’ll try the circuit feeding a conventional bridge rectifier, power capacitors and more linear voltage to achieve, one coil’ve added. More precisely, the full name of the filter cake “p”-type filter.

Half did not have to heat problems as seen in the photographs I used a pretty big cooler, but as far as I remember in the LM3886 and 3875 integrated thermal, short circuit protection features such as dc-ac current.
