Im just using the generics term The electrolytics and the inductors or chokes are a filter network to take the AC component or any DC variations out of the B+ or supply voltage. At lower power supply frequencies the filter caps have to be larger typically 450uF - 2000uF and are a direct short for AC to ground.Chokes are not that common anymore but were placed in series with the load and presented a high impedance to AC. A typical PI ckrt was Cap to gnd then a choke then another cap to gnd. Since heat dries out electrolytics it is beyond me why they miunt them next to the heat sinks unless they have it down to a science whereby they dry out as soon as the warranty is over.
In yourphoto the 2 caps lower right are in the 24 volts supply and should be replaced with 35 volt caps. They produce the symptom of shutdown after a few seconds.
Smaller caps in the picofarad range are used to filter RF or higher freqs.
