I'm trying to design a 12AX7 gain stage going to be used in the next amp. I'd really like to get some comments or feedback of what I have so far.
Now there's two big caps letting all 'ear' frequencies pass. (I might try smaller caps down the road to see whether I like a more trebled oriented boost.) But now, I'm not sure of how I calculate the out and in impedance of the two gain stages. Should I flip the order of the two stages?
Well... if anyone commented the gain stage I'd be delighted.
Edit, I added an updated gain stage.
