Prototype SNES / PC Amplifier

posted in: Audio Projects | 0

This was a 2-Watt/channel audio amplifier designed for Super Nintendo or computer sound cards. This prototype used an integrated amp IC, volume control, power switch, power light, etc. The power supply was a surplus wall transformer, rated 15VDC @ 1000mA. This unit is still in use today by an old friend in NY. This project was a good example of what could be built using some spare parts found in my myriad of parts cabinets and drawers.

Eventually this became a commercial product sold locally in Schenectady, NY to my gamer friends, as well as through the Usenet Newsgroups. As shown in the photo (sitting on an old HP printer) the prototype had a slide power switch with 12V panel lamp for power indication. It also used a stereo 100K audio potentiometer I originally got from Radio Shack. The RCA input jacks and 4-position speaker terminal strip also came from Radio Shack. I wish I still had the schematic and some internal photos to show.


THIS IS A RESTORED ARCHIVE PROJECT AND AS SUCH MAY BE MISSING PHOTOS, PARTS LIST, SCHEMATIC, ETC.
