I took a stab at drawing up a Hoffman-style board for the 5E4-A Tweed Super/5E5-A Tweed Pro (same thing, except for one resistor). PDF of first draft attached. Green boxes above/below board indicate connections to the turrets directly in line with them. Dotted black lines indicate non-obvious connections; dotted red are underboard links. Adjustable fixed bias part is just cut-and-pasted from something else for the moment. .02 caps are drawn as .022; power supply caps are not drawn.
Unverified, untested, unbuilt, don't blame me if it burns your house down, etc.
Did I do it right? Comments, corrections appreciated.
