Very nice set-up! Is the equipment under CD transport a Marantz DAC? Is the amp on the top a Opera Audio Signature amp? - #25 [DenonFanNo2], 06-11-01 09:53忘了講講試聽的安排、細節和條款:
試聽不收取任何費用, 但需交下按金. 還機時全數退回.
這台5687日後會礎b我的辦公室 (中環), 取/還機地點也會在中環或附近的地鐵站.
關於訂機, 價錢, 付款, 運送, 修理與其他事項, 請跟Colin聯絡. - #26 [aliu], 06-11-01 09:56where in central?
- #27 [DenonFanNo2], 06-11-01 10:14"where in central?"
Central MTR is most preferred. - #28 [DenonFanNo2], 06-11-01 10:21仲有仲有.....試聽期暫定為兩星期
- #29 [DenonFanNo2], 06-11-01 11:39網友Richards跟Colin的線路做的5687, 除了可用單管5687外, 還可以用417a及6c45.
- #30 [claude], 06-11-01 22:07Any brothers know where can I buy a pair of match 5687. I have bought a pair of philips 5687WB for my diy colin amp but find that they are very unmatched. The left and right channel volume are different.
- #31 [DenonFanNo2], 06-11-02 09:29這是Richards的755c
- #32 [DenonFanNo2], 06-11-02 09:31claude,
I also encounter the same problem. I use to adjust the right and left channel volume from time to time. - #33 [we349], 06-11-02 10:03hi denonfanno2
近日會試改內部之電容為Rubycon,看一看有何分別 - #34 [DenonFanNo2], 06-11-02 11:28"....但無論如何Colin做器材的意念我是很欣賞,但客戶服務方面就.(可能是對香港客是這樣)"
跟Colin通訊, 有時係一、兩日答覆, 有時係五、六日至覆, 我諗坉曮Y日日check e-mail.
訂機都係咁, 我部5687唔洗兩個星期收到, 部71A舊年年尾訂, 仍然等緊. 夆悼爬n耐無裝71A, 最近至恢復.
不過, 坌J"先寄機, 後收錢"方式, 真係無得complaint喇! - #35 [claude], 06-11-04 21:57Dear Friends,
Can any one tell me the bias voltage you have measured on your coline 5687 amp.
For output tube, I got:
B+(R/L) = 268/268v
plate(R/L) = 239/239v
bias(R/L) = 7.0/7.1v
cathod(R/L) = 66.1/61.9v
For input tube, I got:
B+(R/L) = 132/132v
plate(R/L) = 54.2/55.4v
bias(R/L) = 1.9/1.9v
Did anyone think this is close to yours?
Ah, I forgot to tell you that I use Lite R-core power transformer, 5AR4 retifier, Poshan 10W output transformer, and CLCLC (don't have enough voltage from power transformer to use chok-in) filter circuit with two 10H chok.
- #36 [DenonFanNo2], 06-11-06 16:42No measurement done....no idea! Any other Colin fans can help?
- #37 [DenonFanNo2], 06-11-07 11:36聽過好一段日子了, 竟然忘記給我的5687拍照...
- #38 [DenonFanNo2], 06-11-07 11:39在香港用的, 當然係220V版本.
- #39 [DenonFanNo2], 06-11-07 11:42輸出阻抗只有8歐姆一組
- #40 [DenonFanNo2], 06-11-07 11:43PCB版本係用6x4作整流
