Don&#8217;t you dare put that Heathkit together with lead-free solder! That could tear a hole in the fabric of space time! Also, I dunno about the idea of putting all the components on the lugs and rotary switch terminals first, with all the soldering coming later. The boys at Benton Harbor wouldn&#8217;t have liked that. And you might want to gradually bring the voltage up on that big electrolytic cap up using a variac. Which brings to mind some needed advice: BE CAREFUL! You have moved out of the realm of 12 V DC.
