In Reply to: Sovtek 6B4 data posted by Todduk on March 30, 2007 at 11:34:10:
JC Morrison posted that the Sovtek was built to be a 2a3 and should be used as one. So the NOS 2a3 data is all you need."the sovtek 2A3 is manufactured to match the transfer characteristic of a 2A3 as much as possible. measurements made by us as well as by others (audio amateur has plate curves in its review of the tube, for example. so does costruaire hifi...) indicate that this is in fact the case. you can use RCA's curves, or ours... big schmear. the center values are the same."
