If you want to order PCB, maybe try -Removed by moderator-. They provide rapid prototyping.
Their minimum order is at least one board, the board is of good quality.
To Poland about four or five days.
They now have activities. Can be paid on delivery.

Power amplifier board voltage is high, the LED indicator burned, the test voltage of 17V, with a multimeter test voltage regulator diode voltage 17 ~ 23V, can not find the reason, I hope someone can help answer.
