這些fuses是both end 套住 with pigtail cap.The pig-tail is welded (not soldering) for reliability.
The whole fuse assembly can be 攞出來, by desoldering the pigtail points on the board.it takes just 2 minutes; 容易呢 !
be noted that fuse filaments are soldered to it's end caps with a small piece of solder.The pig-tail caps were force-fit as a post process per customer
request.And, that's it.Never 拉開少少兩邊pig-tailcap 腳.Even 0.5m/m都唔可以; once pulled, the fuse is deformed and failed.
By the way, this picture shows those fuse filaments are in diagonal placement (對角線的).That represented a low-tech manufacturing technology (e.g. cheap cheap mainland backyard factories....) was applied.Replace it with a quality fuse from other "Brand" is highly recommended.

現在冇事, 暫時唔攪住啦.

you can also buy fuse holders from Wah-Fai, SSP.$6 for two pieces la~~
with fuse holders, you've the freedom to apply discrete fuses, from $1/pc to $1,000/pc. {:1_352:}

唔該晒師兄的畫圖解釋 {:1_245:} 請問filaments"對角線擺放"同"平衡擺放"的聲音有什麼分別 {:1_342:} 因為未試驗過!

師兄，前者可以在backyard手作坊製造，後者採用高精度機器生產。個中涉及filament品質控制及熔斷變化等，影響應用效果。

最緊要是沒有影響到聲音, 反正一般FUSE都是好平{:1_245:}
其實用直接焊接在電路板上FUSE的原因是:
1. 廠家減低成本;
2. 廠家減少工序; 還是
3. 最直接最短減少阻抗呢 {:1_342:}

的機賣得唔平, 又賣得唔多, 都要減低成本同減少工序{:1_331:}

賣得唔平都要減低成本同減少工序, that's business !!!{:1_343:}
$1 manufacturing cost => increase $10 selling cost = 10% less competitiveness ka~~

原來另一邊2個大電容側,有2個fuses是用fuse座的, 又唔係全部用"axial lead fuse"減低成本同減少工序 {:1_342:}
若是正常使用器材, PC同IEC都有fuses, 這種"axial lead fuse",是否好少機會會燒呢 {:1_342:} 如果燒了, 一般用家未必識換{:1_260:}

C+Hing, couldn't you tell the difference between a post assembly (mechanically) and an electrical component ?{:1_333:}
器材vendors are not expecting fuses 燒了用家識換. ALL vendors expect to offer fuse replacements at charge$$$$ ! {:1_343:}
