Board drill and component placement guide:
Print on 11x17 inch paper with no scaling and the result will be suitable for use as a template.
Chassis layout guide (not to scale):
This sketch is for reference. While close to scale it is not exact. In the final build the orientation of C24 was rotated 90 degrees in order to clear the pilot lamp assembly. Additionally, the layout shows bias pots and an ultralinear switch that were not included in the schematic nor employed in the build. The power transformer is a Weber Deluxe as noted on the schematic. The Weber part number is W025130 125P23B. The output transformer came from Triode Electronics and was a TF-110-48UL.
Print on SuperB 13x19 inch paper with no scaling and the result will be fairly close to scale.
