I used to implement a rampant LM3886 application BPA300 LM3886 notes will take a lot of time, but I couldn’t find the çizmeside circuit was just a search, I found the drawing but the pcb is double trouble. If you want to make, single-layer pcb design, symmetrical supply circuit, the input amplifier, 220v with soft start circuit for power calculations in case of complete project oscilloscope measurements applied to the Circuit found:)
6 LM3886 is used on BPA300 DIY in the realm of very high quality and are quite popular, including additional input amplifier op amp 7 LF411 there.

Handmade TQFP32 Converter DIP32 Adapter To PCB
TQFP32 in integrated circuits do not require soldering, especially for microcontroller projects, going to work is a handy TQFP32 DIP32 very good craftsmanship In handmade converter pcb solder after filling up with left, right bars soldered onto the sections. In order to facilitate the placement of the chip, the chip will form part of the cut.
In addition to a thick piece of paper pasting onto the pcb integrated onto the chip part of the pcb to secure the plate vidalanıyor. Vidalanıp is used to track when the label for the enumeration of compression adapter is ready for use.
Can you please send me the schematic diagram of your LM3886 300W amplifier.
