The 2 electrolytics, one is chassis ground the other is not . I just checked the schematic and the speaker output
primary does show its 450ohms I'm getting .730k. There is a 70 ohm resistor and it's ok but I don't see a 400 ohm resistor. the 190k I replaced with an array at 186k and the 490k I replaced with 470k .
