thx :)

PS: these yellow cap are USA BC cap, 0.1uF just HK$0.5

By the way, any method to buy some LT1085-3.3/LT1085-5.0 in Hong Kong/Taiwan
are they expensive?

But spend this sum of $$$, price is not a big problem any more

透明的那種電容我猜是 PS ( 聚苯乙烯 ) 材質的, 特性比 PP 聚丙烯還要好。

真的是好發燒的入門級啊 :ale: :ale: :ale:
LED電阻用熱狗應該是追求裝機的"外觀"一致性吧 :eeh:
我全機最發燒的也不過只有 ERO 的電容 :bigcry:
其他都是便宜貨 :x

嘿嘿嘿...
之前幫我同學裝的「旗艦版」也是為了不知所謂的「一致性」,
全用 Holco 電阻 ( 比 DALE 還貴很多... :mad: )
連點燈的地方也是用 Holco... :ho:

Holco, I would not use in Digital Part, seems the response is not as good as Dale :b14: :b14:

Dale in HK is HK$2.5
Holco is HK$4.5 :mad: :mad: :mad:
use Dale in all digital parts and LED parts just to solve the psychological problem..... :haha:

These two WIMA Blackbox, really a good psychological treatment for me :aiya: :aiya:
