Yes, 57 is an electrolytic cap that should be 12 mfd 400 volts according to the parts list from the Phorum library schematic. Someone replaced it with the duo 20 mfd 150 volts and it looks like they used only one section. You can use 12 to 16 mfd 400 volts and the negative lead is not grounded. BTW the schematic I used is very clear.
