Exactly. In my redraw of the Eagle Supre, I labeled the first used power node as node "B" to highlight that point, that node A is not used in a CLC filter. Or at least if it was, it would not effectively be "CLC filtered" and likely be noisier. Thank you for clarifying that.
Just plug it in, man.

Looking forward to seeing more about your project as it develops.

Right now for a preamp I have the clean channel from Tone King Imperial schematic that has appeared on the internet, but with a mid control added. I do not have negative feedback on the PA. May try that in the future

Hi Dave, are you saying that Viperdocs schematic would work out? I have a donor amp that is prime for another Supre Eagle. If you recall I built one in the original iteration, and it was/is a fine amp. In the donor amp I have it has all the necessary elements and a choke to boot.Not sure if the choke is correct for the project. Just wondering if the schematic looks good to go?

Just a note on this terrific amp. The layout shows the 1K 3w R going to pin 6, with the connection to the dropping string at pin 4. I think that wire should be at pin 6.
