1215 - Stereo Line Level Audio Preamplifier or Headphone Amplifier Kit

This kit provides two voltage gain blocks for each channel, full “A class “ biased active elements and special noiseless PCB design (separate audio and power earth rails).

It allows very long cable-driving capability (active speakers etc.). Can also be used as a high quality stereo headphones amplifier (dynamic drivers).

Kit includes all board mounted components and solder for assembly.
