Hello all. Your headache is back.
A power supply outputs its +120V fine. Its +220V output line yields +110V.
That is, C1101 has reversed -10V across it.
Both D1101 an C1101 replaced twice; same result.
Disconnecting the load at the +220V line, still does not work.
The top secondary brown-to-red shows 38VAC
The middle secondary red-to-orange shows 41VAC
The bottom secondary orange-to-yellow shows 90VAC
Bridge +to- shows 164V.
Bridge ~to~ shows 132VAC
+8V; -8V are solid healthy.
Nothing is hot, toasted nor blown anywhere.
- What is the purpose of D1106 ?
- Do +8V, -8V presence control/enable its operation ?
