Phil,
Worked on a Sansui/Orion(UL289X), which is the mfg for the Zenith & Emerson
combos, today. Found a bad solder joint at the output of D509. The symptom
was the same as yours. The connection looked good, but no b+ to the hot.
Resoldering the connection repaired the set. This set was mfg 2-95. I found
several bad solder connections, but the one on D509 "cured" all problems.
Hope this helps.
