Eric;
It probably just needs an alignment, which is not too hard to do on a simple TRF set like this. You more or less need to set it to a station near the mid point of the dial and tweak the trimmers there is such a way that you still get stations at both ends of the dial. Since it's basically an electrified 1920s battery set anyhow it's not going to be a real powerhouse with only six tubes, well five since one is the rectifier tube.
