This chip amp stuff is just too easy not to try.
So Brian and I went ahead and threw together our own gainclone (single channel inverted lm3875). The initial impression was that it was a bit harsh, but otherwise pretty good for the invested money, parts, and time. Of course, this wasn't ideal conditions.. Mono, no shielding, and no burn in. As for configuration, we left out the output resistor, scrapped the rail to rail cap, and tied the positive input directly to ground. The power supply is a pair of HP bench power supplies (on loan from Georgia Tech). So how long do these chips take to burn in? I don't think it would do much good to test different configurations until after burn in, right? The next step is to finsih another one (yay for stereo) , and replace the bench supply with a transformer. --Jordan |
