胡兄:
我一友人在加州p了晱x仿WE91A机器,繻O你的妨~, 可是我看里面的一些零件可能不太像你Z用的, 是改了?
310 去300B 的5容值是 0.22, ? - #25 [doctorjohn], 08-11-06 06:33

胡兄:
我一友人在加州買了這台仿 WE91A 機器,賣家說是你的產品, 可是我看裡面的一些零件可能不太像你會用的, 是改了嗎?
310 去300B 的電容值是 0.22, 對嗎? - #27 [水胡], 08-11-06 09:11John 兄
這是我早期製作91A,部份零件被改裝過,交連電容是0.22U - #28 [水胡], 08-11-06 09:19John兄
早期製作91A,300B是跟原廠AC燈絲,噪音較大.
後期已改為DC點燈絲 - #29 [水胡], 08-11-06 22:4644A完成

my mono 41,42 with a pair of 205D is singing now. - #31 [penndan], 08-11-06 23:05pre amp is 6SN7 pre

- #33 [ptsang], 08-11-07 11:27At the time we started to build the replica WE44A preamp, we have the original 44A in hand as reference in terms of circuit topology, not the sound as a matter of fact because the 5K frequency response makes the 44A only useful in voice reproduction applications. The power supply circuit is still missing(a temporay WE274 power supply was built for testing of the original 44A), I went thru' many of the WE stuff, the 44A main circuit cannot be found in the WE publications of audio amp diagrams. Traditional intelligence tells WE274 is always the solution for WE amplification purposes, trial listening on using 274 and 2x205D revealed the contrary.

- #37 [老吳], 08-11-07 16:17Thank you for your 86B100ma電流表及輸出阻抗接線圖. Look sexy on your 3 piece 44A with 205D power supply. I will consider to upgrade mine after I complete my 86B project. Attached some photos of my 44A. Quite difference from yours on the parts/components lay-out. See you soon.
