2A3 vs. 300B single end triode....

Twl above:"Much depends on the amp design that the tubes are in"

I agree with that.

Below is a comment by Lynn Olson that has cauesd me to experiment with the driver stage a bit. I think it is harder to put a finger on what exactly is causing a particular sound than is sometimes thought.

quote "My limited experience so far is that drivers actually contribute a stronger sonic signature than the output tubes, which are pretty transparent if driven by a low enough source impedance and low distortion.
Arthur Loesch tracked me down at the CES a few years ago, and as we chatted and toured the rooms at the Alexis Park, he mentioned that most DHT's sound alike - if driven by a low enough source impedance and a powerful driver with *lots* of current. It's when they are driven by feeble 5-8mA driver tubes that the characteristic 45, 2A3, 300B, or 845 signature appears. In other words, you'll get loads of that 300B sound if all you're using is an RC-coupled 6SN7."
end quote Lynn Olson

The guy is no fool. Something to consider anyway.

I remain,

Clueless,
How about a choke-coupling from 6SN7 to 45?
With battery power, and ZOTL output from the 45s?
And DHT with 250kHz AC on the filaments?

Craig, I'm just teasing. I love this amp!
You guys are the only ones that I can share it with, because nobody else I know can even comprehend what I'm talking about with this amp. I hope you don't mind that I mention it from time to time, because I just need to share the joy that I am getting from it.

I'm a dealer, so beware! But I had to put my 2 cents worth in. My Sophia Princess 300 B uses a 6SL7,El-34,and 300B.Best I've heard yet, But I've not heard them all. So take it for what it's worth.

I prefer the 2A3 overall for classical such as string quartets, small scale orchestral and jazz; music that rarely utilize instruments where low frequency extension is required. While the 300B gives a better lower frequency extension and twice the power, the 2A3 is, to me, a more musical tube. All things being equal (which they never are), a 2A3 amp with my high gain preamp takes away the 300B's edge in power. That's why I use it over a 300B (though Twl has given me an interest in the 45).
