Proposed Tube Pedal Schematic
Today I drew up a schematic for a 2x 12AX7/ECC83 pedal. It uses a charge pump to get a 12V supply up to approx +45V...
This is my first delve into tube electronics, and overall one of my few from scratch designs I have built so far. Could some of you please spot my numerous errors that I have undoubtedly made? I just hope it's not the entire project...
Notes:
The marshall tone stack in the middle might be changed. The gain and volume divider values I decided to forget about and figure out through testing (I really don't have any idea how my 12AX7's will sound with a 45V supply)
Sooo, thoughts, suggestions? Am I crazy/totally confused as to what I am doing? Or am I actually going somewhere with this?
As far as testing the design, I need to make some orders first - charge pump IC, tube sockets...
EDIT: Dam, just noticed that that first 3.3uF cap should not be there.
