Another day ago, I find this site... is very interesting (I suppose... for me it is...)
//www.tone-lizard.com/LESSON_INDEX.htm
For those that know not of tubes, the author has laid it pretty simple.
Great informer for those who want or like tube amps.
A nice collection of concisely written about and important topics like speakers etc, good to see.
These [especially early] tube amp experiments are what today's tube amps are mostly based on. Some of the good design experiments stuck [modded or not], not to say there aren't 'lost' schematics that have mojo in the ink. The longevity of popularity of a given design most probably determined by user feedback in the performance/price to make categories.
For my purposes, which are quite varied, a good tube amp is determined by the quility of the transformer, and speakers themselves as much as any other three factors...point not well made but get you where I'm trying to go. ie with cheap transformers, and speakers, all the tweaking in the world will only reveal a certain amount of the designs capability. Tubes of course, but they are in sockets and can be A/B's fairly easily, or easily replaced with nice ones.
I just like them, the clean ones, the crunchy ones, I never was one for Master Volume or Distortion channels, but I could most probably aquire a taste for these new Dual Rectifier types...lol.
Yeah, I used to read that site a lot. Lots of info.
