谢谢.您上图的管子大概什么价?可以短消息!那么6SL7有什么推荐吗?ECC35?
我是随便找了个图,你到材料网或ebay搜搜看,应该有的卖.
一般葫芦胆会好过直棒的,ECC32也好过ECC33一些. 但ECC32=CV181不全等于6SN7

6SN7GTB:
Vplate = 200V, Vgrid = -2V, Iplate = 12ma, Gm = 5.4, Rp = 7.7Kohms, Mu = 41
Vplate = 250V, Vgrid = -8V, Iplate = 9ma, Gm = 4.2, Rp = 9.1Kohms, Mu = 38 (典型应用)Vplate = 300V, Vgrid = -12V, Iplate = 5ma, Gm = 3, Rp = 11.9Kohms, Mu = 30
Vplate = 450V, Vgrid = -20V, Iplate = 3ma
(tube data manual lists the 6SN7GTB with a Mu=20 @ 250Vplate, -8Vgrid)
ECC32=CV181:
Vplate = 200V, Vgrid = -2V, Iplate = 8ma, Gm = 4.2, Rp = 12.8Kohms, Mu = 54
Vplate = 250V, Vgrid = -4.5V, Iplate = 6ma, Gm = 3.8, Rp = 15.4Kohms, Mu = 52 (典型应用)Vplate = 300V, Vgrid = -6V, Iplate = 5.8ma, Gm = 3.5, Rp = 16Kohms
Vplate = 350V, Vgrid = -8V, Iplate = 4ma, Gm = 3, Rp = 16.9Kohms, Mu= 51
