Using a Staco Variac with rectifier to make a variable DC power supply?

Hi, I'm looking for some help with the circuit and parts to turn a Staco 3PN variable autotransformer into a variable DC voltage output. I bought some 25A rectifiers from Amazon(https://www.amazon.com/dp/B07TG18DDB?psc=1&ref=ppx_yo2ov_dt_b_product_details) and I have a 590mfd 200V capacitor. I am a beginner at electronics and would like a simple circuit that will work. The rectifiers aren't well marked, one side has AC at one corner and + at the other. Is this doable with what I have?
