The link to his website in the description is the old website, does not work anymore, go to https://franzolielectronics.com/ instead.

Your best bet is to look for the information on his facebook page: https://www.facebook.com/franzolielectronics/

Is this the specifications? https://franzolielectronics.com/alpha-dr/
