This commercial 7W / channel amplifier used two LM383 Amplifier ICs. This final version also had an input selector for switching between two stereo input sources, plus a better case with venting. This unit is still in use today by some old friends, although a couple say the volume control is a little crackly when adjusting it. I sold many of these to hardcore console and PC gamers in the Capital District area or New York.
In the photo you can see a couple of homemade speakers built. The drivers came from a boombox. The TV is showing one of my favorite SNES games at the time. Although I no longer have the schematic, I basically used the reference design published by Forrest M. Mims III in the Engineer’s Notebook II and made two copies, one for each channel.
