6SN7 Tung Sol Reissue Mullard 12AX7 any comments?

I have tried the Mullard 12AX7 reissue tubes in a Conrad Johnson phono stage and they do not look or sound like the NOS Mullard 12AX7 tubes that I was using. The reissue tubes may sound a little better than the Sovtek or EH labeled tubes but they are not Mullards. I went back to the NOS Mullards.

It always amazes me when people comment on products they do not own or have not heard. I have the Mullard 12AX7 reissues and while do look like the Sovteks the sure don't sound like them. They have a much smoother more extended sound and are not strident like the Sovteks. I use them in a Cayin A70T and Cayin MT12A (an EL84 amp that I have not seen in the USA). The A70T came with EH 12AX&'s and MT12A with Cayin branded Shuguang 12ax7's. In both cases the Mullard re-issues were an improvement.
I also have a set of the Tung Sol 12AX7 re-issues and the pair I have are very low gain,the sound seems very recessed and they are a short plate design as compared to the long plate Mullards.
As to output tubes I have not had a chance to listen to the GEC Gold Lion re-issues but I do have two sets of the Tung Sol 6550 re-issues one in an Audio Research CA50 and a pair used in my Antique Soundlabs MG SI 15 DT single ended amp. In both cases (they replaced SED6550's in the AR and Valve Art KT88's in the ASL) they were a significant improvement. To my ear they are very similar to the original GE6550's as I still have one Quad I use a reference. I hope this gives you some help in making your choice.

i have mullard 12ax7 reissue, mullard 12ax7 long plate and sovtek 7025/12ax7wa. i have tried them in my cd player, a vincent cd s6. the reissue mullard is unbalanced, with an emphasis upon the highs. i do not like this tube. the mullard long plate is balanced but has no bloom. the sovtek is the osftest sounding of the three. i know, it is hard to believe.

All right, I couldn't stand waiting for someone else, so I just ordered a half dozen to try in my Atmasphere MA1s. When I come to any conclusions, I'll post back here - probably not until after the new year, though. I wioll be comparing to regular Electro Harmonix, not NOS anything.
Another thing I wonder about is if by the time you get around to trying a new tube type, if the old tubes are so worn out that anything new would sound good, but if you had different tubes all new, then did a shoot-out, you might think differently.

In a neutral system, the Tung Sol re-issue is a honky sounding tube...nothing smooth or natural about it. For a bit more, you can get into NOS Sylvania VT231 tubes...smooth and extended. Good stuff!
