| [#1] troubleshooting - Teac A 2300 S Reel to Reel Deck it is a nice working Reel to reel deck...and only have one funny issue end of tape , once the brake is triggered , it trigger the Main MCB the blue circle is the Brake solenoid , attached to it, it is the tension arm switch K2B and a spark cap i wish to make sure it is safe..and gift that to my friend...haha it was also a gift from a good man..................... delight to learn some more troubleshooting skill......... haha  最後修改時間: 2022-03-08 17:10:45 |

| [#7] troubleshooting - Teac A 2300 S Reel to Reel Deck i 300% feel your question is super logical, and u find it "這樣不合邏輯" is right am also feel ...the things it happened...or the info i given is kind of something wrong..or illogical but..cannot test it now.. haha..cannot pop that MCB at this particular moment it was a new fuse fast blowing type 最後修改時間: 2022-03-08 17:44:35 |

| [#9] troubleshooting - Teac A 2300 S Reel to Reel Deck 正常的降壓牛，內裡也應有fuse，這樣也能觸發MCB，而兩條fuse都無恙，豈不怪哉？ |

| [#10] troubleshooting - Teac A 2300 S Reel to Reel Deck it is a a super CT 1500 1500Watt step down and still good and kicking with a 100V turntable should i use another line of MCB..and run that test... may be it is my line of MCB..issue ? never say never.. thx thx for having this troubleshooting fun with me 最後修改時間: 2022-03-08 17:58:50 |

| [#12] troubleshooting - Teac A 2300 S Reel to Reel Deck yes....yes....i test it ...after i roasting a chicken... 焗緊薯仔整緊燒雞... Haha 第一等 try 搵多一個CT 2000 trnaformer and use another MCB line and run that test.. A little bit later.. Haha thx thx 最後修改時間: 2022-03-08 18:08:32 |

| [#14] troubleshooting - Teac A 2300 S Reel to Reel Deck 呢種情況要睇下係咪用左如下圖般的"老鼠尾MCB", 即是RCBO：Residual Current Circuit Breaker with Overcurrent Protection, 一隻手拍唔響的。  |

| [#15] troubleshooting - Teac A 2300 S Reel to Reel Deck Hi lam Seem very similar to the one u shown, or even the same And interestingly... I am testing it by another line of MCB.. It has no such cut off, for both forward play.. Fast forward.. Rewind.. Etc.. No issue too, it was 100/100 cut off..when it was using with my PC audio line of power Need to triple sure it is safe . Until I give it to my buddy.. Haha  最後修改時間: 2022-03-08 22:37:39 |

| [#16] troubleshooting - Teac A 2300 S Reel to Reel Deck Haha 師兄所用的正是老鼠尾MCB（RCBO）, 表面上看，兩隻手（即 MCB 和 機的 Solenoid）都係正常，但兩者都同時存在隱憂，所以兩隻手一拍即響（trip MCB），下圖簡單地解釋個中原因； 1.RCBO MCB 係用電流平衡方式去檢測漏電同過載，而且用上微型電腦晶片及ADC去實時測量電流，所以普遍有高頻不穩定和過敏情況，於是設計者加左一條老鼠尾用 safety cap. 去接地令靈敏度降低，但結果跟傳統 MCB比較也是偏高，其中也有可能係本身的 safety cap. 失效，亦有可能係電工忘記連接老鼠尾。 2.Solenoid 沒有如下圖般的 snubber circuit, 當年的機器沒有現代 IEC的 ESD, EFT, Surge規格，所以當綫圈起動時引發back emf surge流過電源線去觸發那過敏的MCB, 其實機本身是安全的，以舊機計，大可不必理會。  |

| [#17] troubleshooting - Teac A 2300 S Reel to Reel Deck Hihi... Lam OH.. Thx thx.. 首先知道部機器在這方面是安全的 so nice.. 用多佢幾日證實其他都沒有問題週末就送給朋友 haha.. So happy 多謝羅密歐... 經過你 邏輯嘅question 都知道自己提供嘅資料 一定係 有些不完善.. 找人幫忙要自己盡力準確, 減少浪費別人的好意及時間.. Thx thx.. Learn more than one things from you.. More than just some technical knowledge and some solution Thx 以上兩位高手 令我知道下次電工來... What to check... 每隻學多一點點真好 haha Thx Haha Have a happy day.. |

| [#19] troubleshooting - Teac A 2300 S Reel to Reel Deck Haha... 多謝提醒我有兩個朋友有呢個儀器唔用我問你借嚟玩下先. . 如果係香港... O r target leakage current shall be 0.3ma to be safe . Or still ok with 0.5ma? If it has a leak above 0.5ma.., we should earth that device? Or it is a root cause somewhere to get fix? Haha . Fun... To run some test.. 最後修改時間: 2022-03-09 12:32:43 |
