By the way, the 220Vdc is not smoothed because I have yet to find a capacitor with large enough voltage and capacitance (even in parallel) that is 2-poled in my country (I have 4 poled capacitors but I honestly don't know how to work with them).

@Philomel That's what I thought too, that maybe it would be a simple short circuit. But when I tested it, it didn't give out any beep. It even acted as an open circuit between the poles. The thing is that they have -, +, 2 and 3. I honestly don't know which is connected to what, that's why I don't want to take the risk and potentially blow up capacitors in my face :P.

@Jim Yes, I did see many of those online, but like I said, the problem is in my country. We are currently suffering hyperinflation and undergoing a huge economic crisis, so even considering buying from outside is pretty much out of the question.
