About the Q17-TURBO (P2) PCB

Q17-TURBO (P2) is an open source PCB design by stefaweb, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 190 × 75 mm, with 95 components from 56 distinct parts.

Other key parts include the OPA828 and NDC7003P. By type, the board carries 38 resistors, 22 capacitors, 19 transistors, 10 diodes, 3 connectors and 2 ICs.

It belongs with the audio designs in this gallery.

From the project

The Q17 is an error correction HIFI amplifier based on the QUAD405 current dumping principle.

The natural evolution of the Q17-Mini, this time with two pairs of power transistors, better thermal management, better technical characteristics and the same sound signature with more punch.

An amplifier that will warm up even the coldest speakers.

These measurements were made with amateur measuring equipment. It is better to take them as an indication than as safe values.
