I'd appreciate any and all feedback on the attached schematic.
The first pentode stage was inspired by a discussion between PRR and blandman74 here: http://www.groupdiy.com/index.php?topic=24442.5
My main uncertainty concerns that first stage, as I have no prior hands on experience with pentodes. I.e. calculating bypass and screen cap sizes, intuition for how it will behave with different input signal levels.
Also, on the output. For direct coupling the cathode follower, will setting the preceding triodes plate and thus the cathode follower grid at B+/2 be sufficient or are there additional issues I should be keeping in mind?
I realize the topography is about as primitive as it gets, but I am after something that has some (hopefully interesting or gritty) color to it. On that note, will the given placement of the two volume controls give some control over the distortion? I'm starting to suspect that replacing the pentode with two triodes with a pot in between them will give me more flexibility towards that end. As I understand the current iteration the only stage that would clip with any pleasant effect would be the one directly preceding the output, which doesn't seem very flexible.
