Check over on www.audioasylum.com in the "tubes" section. This has been covered in some detail over there--you'll need to do a "search". Basically, it is not a direct sub--it will work in some cases, but not in others. The direct Russian sub for 6dj8/6922 is 6H23n. I can't tell you whether they will work in BAT equipment--but it may be on the audioasylum site. Good luck.
6N1P near equivalent 6922/6dj8
Anyone know anything about these tubes? How near to a 6922/6dj8 are they? Will they work in my VK3i? preamp? Will check with BAT on Monday, but wanted some feedback now if possible.
