A no compromise SET would limit you to 2 stages MAXIMUM, NO coupling devices of ANY kind (direct coupling), NO filament bias (a source of distortion injection), fast, clean low-DCR power supply, heavy silver wiring throughout, brass tripod mounting of all iron components.Output transformer designed for maximum transfer efficiency and overall performance, with NO preconceived nation or theories about what type sounds best. This is determined by ACTUAL PERFORMANCE of the installed component, not somebody's personal transformer ideals.
Three dimensional internal wiring, with NO wires bundled together for "neatness"-- ALL of them have to be SEPARATED from anyything else, and any wires that cross each other must be at right-angles, and vertically separated as well. Physical separation of all mounted and suspended components is a simple necessity.
