After few tests of the gainclone amplifier I decided to make my own PCB’s for it. On the pictures below you can see the results of my work.
PCB for LM3875 has its own double bridge, place for 2 x 1800uF/50V Panasonic FC, input and NFB capacitors. LM3886 PCB is a typical application circuit from the National Semiconductor note.
The LM3875 topic was discuss so many times on this forum so I will just say: GC sounds GREAT! It was worth building a PCB for it

veteran said:Of course One board for LM3875 costs 5$. The LM3886 pcb is cheaper – 2.5$ because it’s one layer, 70um cupper. All made by Hatron
Those prices are for how many boards?

Price of one board for LM3875 (single channel) was 5$ (in PCB Factory), and 2.5$ for LM3886. There was about 100 of them only for people in AudioStereo forum.
