From the post
Time for a a guest appearance. Sebastian sent me some interesting layouts that might interest some of you. Here is what Sebastiam says about it. The best-sounding amp I ever played through was a friend's Miles Platting 100W head (made by Wilsic Sound during the 1970s in Doncaster, England), which was basically a Bassman preamp going into a Marshall power section. So I did a JFET translation of the preamp and grabbed the "power section" of the model feT and voilà, a Miles Platting-in-a-box.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.
