- #2 [shungyan], 22-05-06 23:51Yes! Recap the power cap is important. Some small cap in the input path, remove the current limiter will improve the bass. Quad amps do not like impedance lower than 4 ohm. Carefully pair it with a speaker it loves is essential.
- #3 [達摩], 22-05-07 16:11如果有原廠電容,就快D換喇,電容超過15年都唔多唔少有問題

- #4 [rcywong], 22-05-07 16:36Quad 405 or 405.2 is phase inverted output.
Swap the speaker cables polarity and test the bass performance. - #5 [mgcmgg], 22-05-07 19:00#2 thanks for your advice ~
I am using Quad 10L, 8ohms 84db. Should be good for 405. - #6 [mgcmgg], 22-05-07 19:00#3 應該係原廠了
- #7 [mgcmgg], 22-05-07 19:03#4 Just tried on the speaker side, black to red, red to black. seems not too much difference.
Anyway, thanks for your advice. - #8 [outel], 22-05-08 11:07師兄,405基本上一定要換CAP, 我每部到手都漏緊汁,生水泡。
- #9 [mgcmgg], 22-05-08 11:43#8 汁就唔多覺有漏, 不過諗住搵師傅換左佢一勞永逸.
另外, 我上網爬文, 可以改細個 input gain 去 1.5v , 但睇唔明點覺 - #10 [outel], 22-05-08 12:23你用34又改細個gain?
- #11 [羅密歐], 22-05-08 12:23如果配合現代的訊源/器材,405的增益的確是偏高的。不過我也認識一位用家,將405配合無源前級,倒也合適。
- #12 [mgcmgg], 22-05-08 21:35#10 無呀, 唔識攪呀 ~
- #13 [mgcmgg], 22-05-08 21:36#11
諗住有部 quad 34 , 配埋一套後級加喇叭齊齊整整 ~ :) - #14 [outel], 22-05-08 22:11我現在都是34 /405, 輕鬆聽歌冇煩惱。
- #15 [416GTA905], 22-05-08 23:05我個部跟佬走超過十年

當年加拿大孭回香港,不過老化recap,改gain,改opamp今日竟然已經回加拿大,不過部機就留咗香港新主人
至好聲是改後用PassDIY B1 前 推sonus faber toy tower,甜潤,低音大心口,音場廣闊,動靜皆宜,印象深刻!
最後修改時間: 2022-05-08 23:05:49 - #16 [mgcmgg], 22-05-10 17:18想問下有無師傅介紹?
- #17 [shungyan], 22-05-10 21:29DIY ok la!
- #18 [spyder], 22-05-10 22:44真係好易的.
- #19 [happyquad], 22-05-11 00:29早前同網友更换電容情况!

想請教師兄們, 剛買左部 quad 405-2 後級返來, 開聲正常無雜聲,
但聽來聽去都好似無乜低頻出到, 聲音有點鬆散 , 係咪夠期要 recap 了?
Recap 通常要幾錢度?
Thanks!
