Dual LM3886TF
Limited Edition

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. AmpsLab recommends our PSU20K50V power supply module for optimum performance.

Please note that due to the shortage of genuine LM3886TF, we can only accept one Dual LM3886TF Kit per buyer. We apologize for this inconvenience because our LM3886TF stock is limited.
