Hey Eric
I took a quick look at the diagram and it sez the volume control should be 3000 ohms. It may be a replacement. How the control works is it varies the cathode voltage on the RF and IF amp tubes. The lower resistance to ground the higher the volume (more RF and IF gain).
24A's and 35/51's are a bit different swapping them may cause your issue. If you have some 35's I'd switch and see if that helps. If not you could add a resistor across the ends of the volume control to lower it's resistance. I'd try something around 5 to 10K
