Connection of powerswitch

Hi everybody,

Attach the connection of powerswitch, wish can help you guy.

Don't forget to add a 2A-3A Slow Blow Fuse!!!

Thanks for your information, after checking, my connection is wrong when soldering at mid-night.

I remember Simon suggested to use 0.5A fuse. Please confirm its value. Many thanks.

Hi,

I am a guy who know nothing about the electric.  ops:

In this respect, I took advice from my friend who is an expert in this field.  
He pointed that the existing switch connection may not be correct. Anyway,
not wrong IN PRINCIPLE. (Please note that it my not be wrong!)

He advice that the connection should be changed to green and black one as
shown on Simon's diagram. Well, changed it.

Secondly, he said that only 6 電容 on the board cannot work because...(forget)
Well, added to 18.

Danger raised:
1.  My house's electric is 233~234v. High? We had checked twice.
2.  After power on, we discover that there is some smell coming from the board.
3.  Later on, we SAW that there is 一縷輕煙 (有些誇張!) coming from the intersection
point of the " 拱橋 ".
4.  The result is the same after 3 time's trial.
5.  Checking with the diagram, he said;

a.  The value of the 拱橋 should be higher than 200v, say, 240v
b.  Because the input current is 240v (more or less), 火牛 200v, i.e. the current
going to the board is 220~240v. The 拱橋 cannot bear the high power and 熔 (?)

Solution:

Any high hands ?   :?

Hi 海記,

As I know the transformer has input and output, input is the red and black one with 220V (remember to short the middle black & red wire) which should be connect to the on-off switch and the power plug at home.

The green and black (200V AC) is one of the output of the transformer and it should be connect to the PCB with 18 cap so it will rectify and output +200V and -200V to the amplifier circuit

If you connect the green & black to the on-off switch, it may cause problem as it should be the output of transformer but not the input.

I am not sure whether I am right as I am new in DIY as well... Any others can confirm on this?

十分多謝亞 KIT 昨天晚上走上我家, 終於攪掂 .....  :
原來我這個白痴, 竟沒有裝上 FUSE .....  ops:

連累亞 KIT 半夜流落街頭 .....
在此再次多謝亞 KIT , 多謝 HIFI FEVER 各位 MEMBER.  =D>

恭喜恭喜! 明天見!
