Well checked the resistors most are Ok.. I will replace the Dogbone's however.. But found a new problem See picture...

Wires from IF can are missing insulation.. And a really mess adding the Electrolytic

Looks like they added 2 caps in Parallel with existing Can .. The Can was 12 Uf at 450 volts.. They added an additional 147 Uf at 450 volts.. ???? Maybe to get rid of Hum.. or maybe not knowing what they were doing...

Anyway a lot of work cut out here..

Skip...
