at least I would be in favor of Wright's output trans instead after listening to ASL's Orchid, 845 and Wright.Again, YMMV

Do you replace it with a Magnequest, ElectraPrint, Lundahl, etc., and see what happens to the sound?Dave van Harn
transformer rolling is basically the same as tube rolling, a few random swaps basically tells you absolutely nothing about the sound of anything... those more experienced in trannie (or tube) rolling can give you opinions, but still those opinions are generally based on a relatively small sampling of circuits.basically there is way too much going on to expect on improving a circuit by tube or trannie rolling, its basically a crapshoot.
what we do learn from these swaps are the "character" of the specific element being rolled... take 10 different 300B circuits and roll the same 300B tubes and the same outputs through them all and chances are you may start to see a pattern of the sound for maybe 7 of the 10 cases, but for the 8th and 9th case they may sound the same, and that 10th case will tell you just the opposite of what the first 7 told you.
and of course to really make this fair, for those 10 swaps, we should probably try 3 different speakers, and of course we can't ignore the room... what about music type, and recording quality???
i was at a friends house where he had a 12B4 linestage, and for kicks we were doing some choke swapping, the circuit was choke loaded and cap coupled to the output... i think i have a good idea of the flavor of each choke, and an interstage trannie could be used in place of the choke to bypass the cap... listening through some various different music and rolling the chokes, basically told me what i had already known for the flavor of each choke... then one of the guys who was there brought out a recording of him playing the violin... i already had my mind made up what i liked best based on the previous music selections, but we went through the swaps, and when we came to the choke that pretty much everybody liked the least up until now, we were all in for a rude awakening... suddenly this was by far the best sound of the day... it was real... based on everything i thought i knew, i never would have bothered, i still don't know why it sounded so good, but it sure did... and everyone agreed... moving onto other music with the same setup, and we all agreed there were better chokes on hand, but for that one case there was magic....
what it comes down to is simply there are just way to many variables at play here to simply judge a final sound by one (or a handful) random swap (s)...the one thing we have to realize is that even if we do feel we have a good grasp on the flavor of a tube, we still have no idea of how someone else is going to use it, and furthermore, an individual interpretation is merely an opinion... and preaching opinions only works if you preach to those with similar opinions... more often than not, the preaching of opinions makes it easy for others who don't feel it necessary to make up their own mind.
