Brimar ECC83/12AX7 CV4004 NOS TUBE

[sevycat]

I am wondering if anyone else has had experience with this preamp tube. I am considering a pair for my Mark V and would like to know what others think about this tube/valve.

I have a couple, got them used, they have a sweet tone. Well balanced from low to high frequencies, very musical sounding.
