Sonic Impact Apple 5.25" Floppy Amplifier

Filed under: Home Audio > Amplifiers



Computers in the '80s were like Model T Fords. They came in any color, as long as that color was beige. If for some reason you're just wild about beige, check out the Apple 5.25" external floppy drive/integrated amplifier mod created by Jeff Kobi. The drive's guts have been replaced by the tiny Sonic Impact 5066 Class-T amplifier, which uses a Tri-mark TA 2024 digital amplifier chip to produce 10 watts at 8 Ohms and 15 watts at 4 Ohms with near 90% efficiency and no heat.


Other parts used in the mod include an ALPS 50K Log Stereo Potentiometer for volume control, a 12V power supply, and a set of RCA jacks and speaker terminals. If you'd like to create your own mini amplifier out of an old floppy drive, Jeff has provided step-by-step instructions at the link below.
