Gainclone amp LM3886

This is my 8 channel gainclone amp based on LM3886.

It uses a 800VA transformer and 94.000μF Power Caps.

I am using only 6 channels to drive my 3-way open baffle speakers with active xovers.

Sound quality is very good with plenty of bass and detail, i am very pleased with the result.

8 x 65 W at 4 Ohm loads.

8 x 50w at 8 Ohm loads.

@cumesoftware Correct. But keep in mind that using active crossovers means that each driver (woofer, tweeter etc) is directly connected to his dedicated power amp channel. No big coils or caps between.

That means you don't need more than 20 watts per channel.

You can read more about the benefits of bi - amplification search google for the following article "BiAmp (Bi-Amplification - Not Quite Magic, But Close) - Part 1"

@cumesoftware Yes LM3886 is more powerful from LM3875. I am using a 35V power supply because i was mend to use is only with 8 ohm speakers. But from time to time i have use it to drive different speakers from 4 - 16 ohms, without any problems. Be aware that i use this amp for bi-amplification or tri - amplification with active xovers.

Anyway if you concern about 4 ohm loads you can stick to the manufacture recommendations witch is a 28 V psu,
