Re: Acbel API1PC36 from an old Mac
The startup resistors on the mains side of SMPSUs have to drop a lot of voltage so it is common, even normal, for the 'startup resistor' to consist of a series chain of highish value resistors all with the same value so that each resistor in the chain shoulders an equal fraction of the total voltage drop.
There can sometimes just be a single startup resistor, but if you can spot two or three equal-value resistors in series they are definitely worth homing in on.
