My layout visually is based on the picture of real "The Who" that I've downloaded long time ago from (I think) Mark Huss website (www.hiwatt.org). The schematic is also an direct redraw from there. I would thank you Mark for all Hiwatt resources he did, massive job well done
My layout is for preamp board part only. The PA and PS is stock to DR-103 100W AFAIK
Comments, corrections and discussion much welcome
