- #19 [rchow], 15-01-20 14:29audio08兄，已問廠商，沒有回覆，Thanks
watches1426兄，已知是停產，所以在這裡揾c-hing幫忙，想知是什麽型號，可否有地方買到，thanks - #18 [watches1426], 15-01-20 13:18rchow兄,
不知徐生有否跟你說,ARC早在大約20年前已經公佈此Mostfet End of life and End of support.
但你仍然可以使用你的SP11,雖然Phone stage RIAA瓜左,CD輸入仍能正常工作.
SP-11多年前,二手鋪已不收,要收就是SP10.
早在90年代SP-11物主紛紛出售.

- #17 [audio08], 15-01-20 09:51Why don't you send an email to ARC for quotation of the FETs with details as in [#12]?
- #16 [41450686], 15-01-19 20:50我估揾到part number都停產啦
- #15 [rchow], 15-01-19 17:56巳檢查師父是這樣說的
- #14 [desktop], 15-01-19 16:57咁啱, 兩粒都壞........我唔係好信
- #13 [rchow], 15-01-19 14:31已交給徐生檢查過，是這二粒零件壞了，説香港已無貨，所以在這裏向各位C~hing們，有沒有人知這二粒零件是甚麼型號，那裡可買到，thank,或在什麽地方可下載，service manual
- #12 [et2], 15-01-19 14:16Pg11
- #11 [et2], 15-01-19 14:16Because ARC grind off all the original part no. so no body can clone.
Contact ARC and you have to prepare 3 things, 1) Color code 2) Q number of the FET, 3) SP11 serial no. ( pg.11)
If it happened in both channels, may be some other reason affect it. Better to find somebody check the Phono stage thoroughly include the power for you.
- #10 [lnchu], 15-01-19 13:58都講過是廠自己color coded FET,我唔知通用2Nx 或2sXX編号。你如果有download 個service manual 有講廠part no.專家睇過我也唔多說。或google 美國佬寄去整。
- #9 [rchow], 15-01-19 12:57Inchu兄，之前已交給新華徐生修理，説這二粒零件壞，香港已無貨了，所以有此問各位C~hing可否幫忙是什麽號型，那處可買到，thanks
最後修改時間: 2015-01-19 12:58:39 - #8 [lnchu], 15-01-18 22:51我也唔眀你兩粒零件都無吸出來check就話壞?
- #7 [rchow], 15-01-18 22:39吾明白？
- #6 [lnchu], 15-01-18 22:26http://elektrotanya.com
自家part num. Example 30007501 FET , Orange White Brown.... - #5 [ck2007], 15-01-18 22:15師兄可能講service manual.
如果有我都想知 - #4 [rchow], 15-01-18 19:50manual 是無寫
- #3 [rchow], 15-01-18 19:34Inchu 兄,Thanks
- #2 [lnchu], 15-01-18 18:45Audio Research color coded FET. 唔好當原子粒他. Download 個 manual有part no.
最後修改時間: 2015-01-18 18:49:28 - #1 [rchow], 15-01-18 16:24請問c-hing 們知不知這二粒零件是甚麽型號，去那處可買？phono用，Thanks

請問audio research sp-11 零件
William Z Johnson設計 SP-11 Hybrid已註冊專利,就算一般機有問題,也不會獨立賣零件.
一般情況下建議你找ARC當地經銷商協助.

大家如果有興趣,可以看看William Z Johnson專利註冊全膽增益電路及SP-11 Hybrid電路(原子粒(FET)+膽)
Hybrid電路輸入端(P-channel JFET ),還有莫屎忽"MOSFET"作低阻抗輸出.複雜!
