The Electronics Universe

Hi folks. I know this is an older post, but I found the video very interesting. I recently dug my Eico 147 out and dusted it off. Plugged it in, and immediately got the bad hum. Trying to source the filter caps, I noticed a huge difference between prices with radial and axial caps. Am I missing something? Would I be able to get away with just using radials?

Any help is greatly appreciated.
