The Mullards are truly great in guitar amps. This is part of why they cost so much. In a 70's Marshall amp they roll off the nasty grit in the high end. Sell 'em to a guitarist: we love them! Mullard pre-amp tubes are highly sought after also.I have new JJ brand E34L's (that's no typo, they ARE E34L's) in my Dynaco ST70 and they sound as good or better than the tubes they replaced (Tesla's). (Of course the Tesla's were on their way out when I replaced them- but I don't feel like the JJ's are giving up a whole lot, if anything).
I think we are getting close to a period where new production tubes are going to hit stride. Also,the Chinese are going to get really good at manufacturing tubes in a few years-so we'll likely have a supply of them for a good long time.
