A matched pair of JJ EL84's, two hand picked high gain ECC83S's for V1 & V2 with a high gain balanced ECC83S for the phase inverter in V3 問題1.上面文字說有2隻ECC83S's是for v1 & v2,一隻for v3, 我如何可以知我amp上那個位是v1 v2 v3 左中右??? 問題2.jj ECC83S-HG-B x 1即是high gain balanced ECC83S? 那jj ECC83S-HG-K x2,,,,,k是什麼?? 問題3.一直以為preamp tube買3隻12ax7便可,,請問high gain balanced ECC83S 的用處? 謝各前輩的指教~
問題1. Check Laney Website , VC15有說明書 http://www.laney.co.uk/show_downloads.php?prod=vc15-110&rid=2 問題2 我建議你直接寫mail問Eurotube 問題3 換VC 15 preamp tube只需買3隻12ax7便可 Power Tube 不一定要一起換
回我知道的 問題1.同常V3是相位管,最靠近放大管的那隻 問題3.balanced ECC83S ,你的AMP功率管是推挽放大方式, 需要一隻X7做分相動作,(把正弦波分成上下半波),有挑過balanced的分相管用再分相上面會比較好.
