The chassis number is good. It is listed as Sams 1076-3.
DO NOT buy the Sams for $22, thats a last resort. As far as repairs
go start with the most major one. Dont blindly recap or replace
tubes that check weak. Most old Zeniths come to life & work
fine with questionable parts. Its just the way they are.
Best is to post a pix showing the symptom. True content from a
VCR or DVD are best. Test patterns can also help sometimes.
