Reviving this thread to ask if a fellow Spectrum owner can check their manual and confirm how many pages the schematics are.
The yellow paper scanned images show two lamp driver schematics part #'s W-1182-3901 & W-1182-39.
The white paper scanned images show only one lamp driver schematic part # W-1182-39.
Perhaps someone can upload the white paper scan of W-1182-3901?
