mine have the valve art kt88
and a JJ12ax7's I dont recall the 12at7 tube. the 12ax7 is one of the tubes that we played with when Angelo was in town,
I agree with the same conclusion that he heard also. a tube that was supposed to sound better, but did not.
Bob had a good time with that one, on paper they looked and specked out the same, but sounded way different.
night and day. took all the highs out and smooshed all the sound into bleeaaach.
on my sunfire pre I heard the same thing, before I put some amprex tubes in, then the top end got way better...
tube rollin for you....
