Nice set, My 25MC33 chassis looks very similiar. Zenith didn't really stray much form their chassis layout or design. Good thing, My HV slowly powers up, softly AND smoothly. Mine is very reliable, GREAT idea to have heat sink on power Xfrmr & breaker instead of outdated fuses that need to run around and get replacements--great design overall. My set has the cool tri colored logo to signal a color TV, I guess all old Zeniths or most had this 3 color badge?? Seen similiar bigger badge on older Motorola 21" color TVs.
