- #1762 [com-buddy], 25-11-14 23:23KH-O92 配什麼器材便出什麼效果, 相信雨果易老前輩很清楚. 亦曾经用它監製了不少作品.
要嘗到其真正實力,配上同檔次前級是少不了.
KH O92 其重播古典樂之澎湃及層次感; 是當代德国錄音産品其中典範. 希望師兄樂在其中. - #1761 [Hahayanyan], 25-10-26 06:37Thx for sharing....
實在令人心思思,去收集這些pre recorded
確實是一套簡單已有趣的組合
有部分維修零件已經到了,應該可以令到我三個不同的revox 正常運作 again
正在閱讀092的 資料 -
- #1760 [uat506], 25-10-25 23:19我呢台係靠早期的OTARI 5050 deck 聲音都比較後期的為有味道。 而呢對O92 Active Monitor Speakers 一貫Clinical 但係冇其他大部份有源喇叭嘅過分放大粗鞋 聲音- 2個字-
’恰當‘-好似飲完杯熱辣辣嘅薑汁撞奶,再即刻食啖北海道牛奶雪糕咁, 亂又滑,但又清清楚楚。
家陣啲音樂檔案隻隻都話「無損」、「Hi-Res」,清到好似入咗手術室咁。反而開卷帶把聲,就係有種「唔完美嘅靚」(特別係4T music)佢有啲Resolution「瑕疵」,但就係呢啲瑕疵令佢特別有人情味自己自己鍾情的Movements)。 今日聽咗四集 柴可夫斯基Symphony,好滿足:)

可否介紹一下這對 speaker 的聲音?
整體表現怎樣?沒有經過前級,如果邊個前級的分別又會怎樣呢?
有趣
thx thx - #1758 [uat506], 25-10-25 12:00今日終於嘗試將部老爺「開卷式錄音座」直出插去對Active Monitor Speakers度聽!呢部駁落現代嘅有源監聽喇叭度出聲。:)

- #1756 [hahayanyan], 25-08-02 16:36嘩呢一種大音帶我幾乎從來冇見過真嘅,喺ebay都好似見過一次
十分罕見的東西
8 tracks big tape 就久唔久見到 - #1755 [info2k], 25-08-02 16:31

第二部搞嘅係Studer A807, 由完全摸不着頭腦,到知道部機來龍去脈7788,整吓停下,整吓停下又半年。對我來說,如果唔係自己得閒,識整同有時間,B77 如果多問題的話,真係唔值得投資時間或者金錢落去搞。
反而啲Studer, 因為始終係專業嘢,設計、零件、工藝,及方便維修的程度,B77完全冇得比。覺得Studer啲機相對真係值得俾心機及資源去整好佢。嚟緊將會買入及調整另外一部Studer: A-810…

- #1751 [hahayanyan], 24-08-12 01:43Have ordered those cap and other components for a77, B77, A700. And 2 tracks machine from Teac and Sony
The B77 I have, is still good but end of each tape, speed not stable, I guess it is related to thsoe cap or other cap..
Am thinking let's go a few. Of few of them.. And get a Philips Or Telefunken, having a feeling I should not keep more than 4.. (I may have 8 or 9 now)
最後修改時間: 2024-08-12 01:47:20 - #1750 [dlld], 24-08-11 23:33B77 MK2 ,可以參考相片。個3粒 new 電容 for capstan , left and right spooling motor

最後修改時間: 2024-08-11 23:34:19 - #1749 [hahayanyan], 24-08-11 07:14Able to get back part of the 21 V,
end of tape bulb and sensor work now,
Capstan motor still not running,
and takeup right reel motor not running haha - #1748 [hahayanyan], 24-08-10 22:25Remove 30 wires...
應該夠位做嘢...
Pcb 背後有11條線直接solder上去, 唔夠長拉出來, 但夠位做嘢, 做好定位應該唔需要整甩佢.. Haha
佢哋原本嘅安裝方法一定係連埋火牛這塊板...installed Together
today 要去做其他事情要停一停休息休息 for that ... Haha
真係要佩服細心全機 翻新的 發燒友, 唔簡單
最後修改時間: 2024-08-10 22:26:57 - #1747 [hahayanyan], 24-08-10 20:13That roll of cable and above..
About 19 wire to unplug
Pcb 背後仲有三組 secondary AC cable hard soldered to the back of the pcb... 安 常理 應該夠長, otherwise revox could not assembly it haha 但願如此
好準備好label先至做這件事
觀察 點樣影清楚啲相... Haha before I remove those wires
這些經驗 都是要慢慢累積 才能減少錯誤
最後修改時間: 2024-08-10 20:16:50 - #1746 [hahayanyan], 24-08-10 20:08Haha...
Some little and positive progress
Remove the hidden screw behind the solenoid... No need to remove the take up motor
Need to remove the top power socket bar (2 screw only) and the, otherwise the solenoid cannot be remove
似乎要unplug 27 V DC 一排電線.. pcb先係至可以褪到出嚟
最後修改時間: 2024-08-10 20:11:27 - #1745 [hahayanyan], 24-08-10 18:14真係need 耐性,
再進一步要拆咗take up motor and brake solenoid, 先可以拆開呢塊pcb for further work
如果你哋玩開呢啲東西, 這些問題都是遲早的 haha 選擇嘅係自己搞定係, paid for services
Haha
最後修改時間: 2024-08-10 18:15:08 - #1744 [hahayanyan], 24-08-10 18:13其中一個原因喜歡玩這個東西
係畀我一啲實際嘅 材料去學習
This A77, Capstan motor not running, End of tape bulb 唔著燈 = lost 21V
這個 是 學習維修的 小學課程, 希望透過這個東西 學習, 如果成功修復, 不需要問專家意見, 我就覺得自己升班喇
Haha
1) The transformer not dead, all secondary normal
2) 21V real dead dead
3) take up motor working, means d101 not yet dead,could not reach the point for further measurement to make, hence next step
4) need to remove solenoid and the take up motor, otherwise could not remove the pcb for further checking and fixing
Fun and 訓練耐性 and learning, 雖然這個機器都係幾千蚊, 可以學習嘅嘢價值高很多, 維修好東西 有意義
