RE: Perhaps you are ready to step up your learning.

91, yes you are correct. I am trying to learn as I go along. I have been experimenting with several modifications of the amp over the past 8 months. Some mods I understand why/what/how and others I am at a loss and ask many questions. I do read quite a bit, but in the end I do rely upon the good folks at AA for much of the learning experience.

It is fun to learn electronics and apply it.

The purpose of my build is quite simple: I want the best sound possible, to my ears at least. With regards to the current situation, the amp has great dynamics/transients and texture. However, I want to smooth out the sound with a bit of warmth and fullness. So, Dave Slagle was kind enough to point me in the direction of modifying the current 6C6 driver and making it a triode. This was a first step to see if the triode driver moved me in the right direction. Yes, it did indeed. The only issue with the 6C6 driver is that the output is too low, but otherwise I enjoy the sonics. So, I posted this latest post to see what triode driver tubes would do well with the 2A3. It appears that the 20B might be in the right direction. I like the 20B as it would require few modifications from the current schematic and I "might" be able to supply the filament with battery (5V, 1.4A). So, I am learning bits and pieces. Doing research on my own and asking many questions.

I appreciate your response. Keep the good stuff coming.
