out on the table... probably good for 2 watts or so
i guess the ground trace that goes all the way around
your front end board isn't giving you any trouble?
I assumed that the large power resistors were used for a dummy test load.
As for the ground trace going around, Mark Finnis did it in one of the first DIY Aleph amplifiers a long time ago in his pcb layout without problems:

I have seen others do the same layout also.

thanks for encouragement,say something about power resistor,
when i first saw soz amplifier, i think i should build this. so i bought 8 dale power resistors, but at last i did not finish it because their huge heat and weight and money and space
so i decide to build alphe serial. when i match mosfet irfp250, i found these power resistor is useful , three resistors serial can get 24ohm, i use 30v 1A to match mosfet.
by the way i think these resistor can build 30w soz more than 2w.

nice looking amp!
HAHAHAAH those power resisters are more than 2 watts more like 40 or so. those are huge.

there is no speaker and corn in which place i told you.
if you want to buy speaker, you should go to mei-ruo-cheng in xu-jia-hui. or hifi-plaza of qu-fu-lu , maybe in qiu jiang road has some speaker, but they are all low-fi cheating speaker .
to moe29:
my amp has some noise ,i am checking now, so i cannot tell you
sound quality . but one thing i can tell you, bass is good that i like very much . better than korsun amp (Red Rose Passion amp oem by korsun) i bought before.
