This listing is a SE power amplifier. The output stage is making use of a power JFET LU1014D though obsoleted is still readily available in the market. The circuit is based on First Watt's F3 amplifier.
PCB dimension : 257mm x 35mm
Thickness : 1.6mm
Copper thickness : 75um ( 4 times of standard thickness !)
Finishing : Gold plated with double side solder resist for maximum durability
This listing contains two PCBs so that a stereo amplifier can be built with one set of this listing.
We provide schematic and part list to buyers by EMAIL( to be attached to the shipment notice).
