What a mess.
I don't have any definitive information but a 1k 2w resistor, a 1uf film capacitor and a 10uf bipolar electrolytic will probably be good enough. Since I've found no reliable 10uF bipolar electrolytic caps, I use 10uF film caps.

It have small voltage coming from separate winding in the transformer. But when I test voltage there is no voltage. I am just seeing one winding connected to two diodes. Picture attached.

Both sides winding is connected to two separate diodes. Picture attached.

If it's completely isolated, you would have to measure across the windings to measure the voltage.
If it feeds a 7815 type regulator, place the black probe on the ground terminal of the regulator to measure the input and output voltages.

The Zener has to go to a ground reference. If it's a positive regulator, the anode of the Zener will be the reference (black probe).
4v going to the SD pin of ir2184s but no oscillations. Input signal is attached.

I have 4v black probe on com and red on pin 5. This is the same voltage coming from isolated windings.
Com is pin3 of 21844.
I placed on negative rail now and I am still only getting 3.5v.
I removed outputs and 21844 and still only 3.6v
Anode of zener is connected to pin1 of transistor. Pin1 to pin1 no voltage. Pin1 to pin3 2.3v
