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.

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
