hard work
Nice work!
Nice music will comfort you, soon.
By the way, if you got the components in Shanghai,
could I know where (address) you got? Thanks.

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.

John-china,
Shye shye ni.
My kind Chinese frieds wrote down the road names in Chinese.
They however do not understand "ke ji jing cheng."
What is it?

thanks for encouragement
to jh6you:
"ke ji jing cheng" is "science beijing building" on beijing east road.

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.
Re: thanks for encouragement
Shye shye again.
I will visit there and take a look around,
hoping they will also sell speaker corns and speakers.

to jh4you:
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.
