This is my stereo LM3875 PCB that I put together over the last few nights. I designed the board around a scrap peice of board (3x2) that I had left over from another project. I removed the unused pins to allow larger traces. It is powered by a 160VA 20-0-20 from Plitron, using only a single bridge (for now). I'm using 1000 uF caps. I haven't had much chance to experiment with it yet but in my initial listening tests there was no humm in either channel. I didn't get much of a chance to do any prolonged listening tests (I have 3 year old triplets, spare time is a real luxury 😱 ). I also have a chassis design for this which I might post (made mostly with 1.5" Aluminum angle). The initial plan was to combine 3 of these units in a single chassis with a 750VA X-former as an HT amp, but I may be using bridged LM4780's instead.
