I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode

@ghdprentice: I, and presumably atmasphere, and all other rational thinkers, would rationally conclude that your amps are optimized for triode topology...and, necessarily, that the ultralinear topology was added, presumably as a gimmick, to presumably, attract more purchasers. Let’s hope so anyway, as the other option is that the amps are not optimized for either topology and that you and the other folks just like the same not optimized topology over the other not optimized topology.

LOL, those that agree with you are rational and those that disagree irrational. Argument from incredulity is a logical fallacy.

That's not what I said viridian.  What I said is that there are two rational conclusions that can be drawn from the information provided, and that for ghdprentice's sake, I hope it's one conclusion instead of the other that he is experiencing.  If you think there are other rational, not irrational conclusions, that can be drawn, then please, tell us what those are. 

That is hardly all that you said, but I appreciate the back pedal. We will agree to disagree and leave it at that, logical fallacy, or no.

From a design perspective, ultralinear taps must be added to an output transformer at the manufacturing stage. They have a cost associated with them, a PP output transformer designed strictly for triode operation would be less expensive without the UL winding. So if the manufacturer spends the extra money for a UL winding they would, seemingly, have optimised it for the tube type and circuit.

No back pedal. I’ve told the forum what I said; please tell tell us what you think I said.
