Hi Jon and Welcome!!!
Well you've got a nice set there. Antenna should be as long and as high outdoors as you can get it. Away from power lines and metal objects.

Sound like it's over do for some service work. Motor-Boating is usually cause by bad bypass condensers (caps), bad ground connections at ground lugs, and or missing tube shields. Would recommend replacement of all paper, Bakelite,and electrolytic caps. Wouldn't hurt to test the resistors while your in there too.

This set is a little more complicated than the average bear. If you enjoy working on old sets then it would be fun to do but it's not for the first timer.

Definitely replace those caps before you play it for any length of time as they can short and damage hard to get or replaceable parts. The good news is when you get it working properly it's a GREAT sounding set that has GREAT coverage for the shortwave band.
