Dual LM3886TF

This pcb consists of two LM3886TF amplifiers. With it, you can easily construct a high quality stereo amplifier. Other uses include bi-amping or multiple channels amplification.

Only quality components are used. No ceramics in the signal path. In fact, the input which is often an electrolytic capacitor is a 2.2uF film cap. Feedback cap is a silvered-mica. All resistors are 1% metal film. A bit of a luxury for a chip amp.

The board is fairly compact, measuring only 4.3" x 1.6". To keep to this size, the power supply filter caps are not on board. Users have the choice of the PSU20K or their own power supply.

The Dual LM3886TF is a two channels pcb and is supplied Unassembled.

To complete the amplifier, the following are needed
1) a power supply consisting of a power transformer, filter capacitors and a bridge rectifier
2) a heatsink for the LM3886TF chip amps.
3) a metal case and the necessary connectors
