於EBAY買了支GZ34, 但賣家說送錯管子:-
I just realized that I accidently sent you the wrong 5AR4 tube. The tube I sent to you is a 5AR4 New Old Stock Code Fj2 B1E1.(7 notches) Test results 62/62.The tube you purchased was a Used 5AR4 code F32 B3A4. Test results 60/60.  Since this was my error if you would like to keep the NOS (the better of the two) tube that would be fine.  If you would prefer the other tube you can return the wrong tube back to me and I will pay the return shipping via paypal and send you out the correct tube that you purchased.  The tube that I mailed you is a better tube but it is completely up to you.  I apologize for the mixup.  Please let me know what you would like to do.  Again I am very sorry for the mistake.
Fj2 B1E1 是什麼管子???

我有部怡通WorldWid97回歸版前級VP3a Ultima Preamplifier , 但部機出現問題, 於後級開大聲時會有HUM聲及接觸前級機身有會有回音(包括轉動VOL掣), 所以後級不能太大聲, 用前級開大聲就汲有問題, 是否VOL掣出現問題?
Fisher X-100為合併機, 加前級有否提升作用?

已退回, 感覺賣家有心誤導, 如這個月沒有於這帖學習, 可能已要下單環
而賣家信用值非常高.............

最近部 Fisher X-100 燒了火牛, 不能修好了, 故將購入以下Pilot套裝代用, 順手升級:
Pilot SP210: 4支管子 - 12AX7 12AX7 12AX7 12AX7
Pilot SA260: 9支管子 - 12AU7A ECC83 ECC83 EL34 EL34 EL34 EL34 5U4GB 5U4GB
於早前承蒙J兄之指導購入使用之Vavlo碟片環EL84及雙圓環GZ34就變了不合用了, 而新機只是跟普通管子, 故再次請教J兄如果BUDGET約為$2500-3000, 應更換那些管子較有效果及有什麼介紹, 先行謝謝

那$3000不足換全套了, 如選擇性更換, 應先換那些較有效果?
現時前級管子: 2支JJ ECC83S, 1支美制12AX7A好像是RCA, 1支CBS美制X7
現時後級管子: 5U4GB為2支美制RCA印上BL及AZ碼, 12AU7A也是美制好像是RCA底部有26字碼, X7為2支原廠管子不知道牌子底部有1及15字碼, EL34是4支日制管子印有Reali?t? LIFTTIME
