| [#1] Simple question about a transistor This is a BC414B And accroding to the data sheet.. The middle leg is Base... Accroding to the photo.. It kind of say.. The left is the base And I did a simple diode test... From the middle leg to left and right.. It has 0.672V diode drop... Seem it is same as the spec data sheet.. Or I am stupid and think too much.. The B C. At the photo is only the model no.... Haha Stupid question... This MC pre pre has 4 of them.. And one of them behave very strange.. The right behave like a Base Thx for reading... Haha  |

| [#3] Simple question about a transistor Yes I think so.. As 3 of them from the 4... Confirmed middle is the base Apart from one of them... The left to middle.. Left to right.. Measured just like the left is the base, guess it would it is the faulty one Thx thx Haha |

| [#4] Simple question about a transistor 這兩天開始假期搞搞震 先後搞壞咗一部 tube MM phono stage, smoke a 10uf 400V cap 跟住今日就搞壞咗一部 solid state MC pre pre... 目前 不專業地判斷 is BC414B 放假冇玩具玩好痛苦呢... But ultra lucky... 多謝羅密歐師傅 送給我的虎年禮物 Haha  |
