Does anyone have any info on a tube guy who might carry this tube. NOS Mullard CV4004? I want to slam one in the V1 preamp slot in my Marshall JCM800 reissue. I als ohave some RFT NOS 12ax7s which I have used before and sound great. Also have a couple of new no nameer 9th gen CHinese 12ax7s which also have pretty good tone. This way ill have some options going for my tube choices. I have heard that roughly 80% of your preamp tone comes from the V1 slot. Thats why I only want to buy (1) NOS Mullard CV4004. And at $100 bucks a pop thats enough! THere is one other thread that mentions websites that offer NOS tubes and such but none of them carried this CV4004 Mullard NOS? One had it listed as "Out Of Stock" I sent him an Email about letting me know when hell get some more in. If anyone has info on this particular tube please let me know! Thx!!
