kt88 pushpull 1997 old review

KT88, 12BH7A, EF86 線路 90% 似 Hashimoto_KT88_PP

1997年歐陽Sir提供線路及悉心教導
可惜已失去聯絡,想多謝都無辦法

甘就用左十多年


國產 5K-PP UL 100w 輸出牛

(吾好問點解搭得禁恐怖)

新近粗暴加建LT1083 6.3v 燈絲穩壓 AC 6.3v -> DC 6.3v 供EF86 x2, 12BH7A x2
因為原來AC6.3電壓吾夠高所以不能用LM317轉出DC6.3

LT1083, LT1084, LT1085, LT1086 都係low drop voltage regulator
分別係max load 7.5A, 5A, 3A, 1.5A

(吾好問點解搭得禁恐怖)

好一隻日本牛6.3v5A吾用偏偏用隻cheap3v-0-3v 20VA 比KT88 x2燈絲
(吾好問點解搭得禁恐怖)


好聲/吾好聲 集於一身! 450v 33uf
呢隻水塘仔真係好好聲的~ (重係又平又靚!)
但比我用到甘既狀態~ 漏電難免~


表面風光內裡XDXD就係呢款~ 機腳都無錢買~
隔幾年就手多多改下~ 左改右改~ 而家好好好滿意~

正所謂十年老餅要翻身
我打算再做一部全新既

有無朋友介紹電原牛及輸出牛??級數同舊機差吾多得啦~ 謝過~
($8.5K 一對 Tango Output 我無錢買)
