It has the Magnequest DS-025 OPT, connected to the 16 ohm tap.

So, it is 2.5K primary and you drive 8R speaker with 16R tap. That makes the 2A3 loaded in your case with 1750R. I think it is necessary to know in order to put the things in perspective. In my case I think I will (at least try) to drive 2A3 with muck higher impedance, as high as S2 “break up” would allow me to.

It arrived today. I will set it up this weekend, but I am still not done listening to the other tubes yet, and I will wait until that is over to avoid confusion. I will go back a re-listen after adding the PP2000.

Hm, I think it might be very interesting ride and I think you might as the result to go much bolder with loading, it you have power to drive the Titan upperbass horn.

I do not have them any more. I had listened to them in the past. My recollection is of burnished brass. Warm, brilliant, rounded. Excellent sound in their own right, and again it is splitting hairs between these and the other top grade modern tubes, but that is what I am doing. It is like comparing the chess games of Alekhine or Tal to that of Kramnik or Kasparov. All are geniuses, but the differences between the modern and hypermodern styles are obvious.

Very cool association. Thanks, Adrian.
