Mullard CV4004 in CF ?

Hi All!

I just got myself a pair of current production Mullard CV4004 to experiment.

The target is a 2204, with a TungSol RI in V1, Chinese 12ax7 in v2 and Sovtek LPS in v3.

First I tested the new tube in V1, but liked the TungSol better.

In V2, however, I liked how it sounded compared to the chinese. It seems to tighten the low end a bit, in a way I liked. Seems more clear.

So the same old question is: is it ok to use this tube in v2 (CF) ? I hear the TungSols and regular Mullards have problems in that cathode follower position, but what about the CV4004? :scratch:

Any experiences with this tube at this position?

Thanks in advance!
Fabiano

I have tried Mullard's and Tung-Sol's in V3 , But the one that works.. At least for me, Is the Sovtek LPS... I love it in that position..... The Sovtek LPS is in all 3 of my Plexi builds... I never tried a CV4004... Sorry... :scratch:

A genuine Mullard CV4004 is very robust and can stand anything you throw at it.

I use them in the PI or in a modded amp in V1 to help with micro phonics.
