The Sovtek EL84M is a rugged military issue EL84/6BQ5 that can withstand higher plate current than any current production EL84, and is a suitable replacement for the 7189. The Sovtek EL84M has a clean sound, and nice balance. Good if guitar players want an alternative from the warm distortion. Great for hifi applications. Very smooth sounding and tons of headroom.

- Mesa Boogie Rocket 440 retube(Sovtek EL84M/ your 4 x 12AX7 tone kit) Review by Sean
Doug, you are a genius. Installed my tubes yesterday and now my Mesa Boogie is a completely different beast! First, the hiss I’ve been getting is gone and secondly, the crunch growls when I kick it in and the clean channel is just awesome sounding. I don’t think my amp has ever sounded so good!
Thank you very much Doug for responding to so many emails from me with ridiculous questions. I will post this outcome on the Boogie Board, so hopefully more of us Mesa Boogie owners will go to you for their tube needs!
