I picked up this 1951 Hammarlund SP-600 JX-1 from the family of a friend of mine that recently passed away. It was in an unheated garage. Before the video, I bought it up slowly on a variac. I also cleaned it off with an air compressor and a soft brush. It works! Its main problem is that the tuning knob won't turn the dials. From what I read; this is a common problem. I demonstrate my getting to know the radio and check it out.
From what I read; it is recommended that this receiver be recapped. Listening to it for long hours could damage the resistors. I've recapped a few radios, but not sure that I want to tackle this one. I have other projects going, and this one has 50 capacitors in it.
Here is a good link to information on this receiver:

Enjoy.
