[#26471] Leak Club for Leakies or Leak user they solved it as i said. diy a voltage divider at the input. 最後修改時間: 2014-04-22 18:39:18		Not-So-GoodSamaritan 正式會員 14.xxx.xxx.184	2014-04-22 18:38

If my memory serves me, LEAK TL12.1 gives full its output power at 0.25V of input! That means it is extremely sensitive.

And it means MOST pre-amps with 1V or above driving will overdrive TL12.1 even at very minimal volume level, e.g. volume knob at 7:00 to 8:00, or before 9:00 o'clock.

Vintage preamps are particularly disadvantageous driving TL12.1, because any inprecision in their volume attentuators will be augmented by such a narrow range for the power amp's full output.

A voltage divider is a practical way as NSG reiterated. I bet Hugoleehk has not gone through the previous pages here. Solutions have well been mentioned.

Hi, may I know your real concern? If there is none, you may just sit back and enjoy the music. I am also using 50c, Leak amps driving LS3/5A. Personally, I find that 50C matches very well with Leak amps. The shunt resistors method is popular and commonly used but direct feed in might be your preference. Like yours, the volume level is set around 8 o'clock for sufficient sound level.

KY (Rsbn589) has it quite right.

But FM Accoustics preamp is solid state I guess; matching it with vintage tube power amp as TL12.1 is another challenging matter.

Thanks all brothers.
Problems with matching 50C with 12.1 now in my system is that thte pleasure range that can be controlled by volume button is too narrow.....

從 Leak ST20 中偷師的最簡單保護 "裝置"... 不正常升溫令電阻腳太熱溶降了焊錫自動跌出, 保護了一支 KT66! :)

起因...

Jensen/Angela PIO 交連電容漏電, 引起過高屏流通過 KT66. 但這是灰黑色玻璃的 Kt66, 它的屏發紅也看不到! 100V 耐壓的電解質陰極旁路電容也承受不起 (在很短時間之內電流是正常電流 3倍或以上!)... KT66 的屏極當然會更紅, 霎時之間陰極電阻(仍然新淨, 無被燒黑)的焊接開了路... KT66 獲救!

電阻自動跳開

100V耐壓也迫爆, 電壓可能已經升上 120V 以上

電容竟然變了支 600K 電阻!

換了兩隻電容

一切回復正常!

(分享完畢! :) )

早前更換出漏電的交連電容, 用了一段時間之後, 早兩日測試這對用了 5年有多的 monoblocs (Leak TL12. 的仿製)... 雖然每日用上幾小時連續 5年多如是使用它們, 每隻 monobloc 現在的表現仍然十分 "配對". 表現 "配對" 是播出 3D立體身歷聲必須的條件, 而且是最重要的條件之一! :)
