MrFixr, I double checked and have all the proper voltages between the computer supply and a stack of 9V batteries. The original grid resistors mounted on the tuning caps are open, hair fine wire, so I transferred the good ones from the parts set that measure around 350 ohms. We’ve done away with our landline phone and I have made my old phone line out to the pole a long wire antenna, guessing about 60’ between what runs up the side of the house and then out to the pole, plus whatever additional footage inside the house. It works quite well with the added benefit of now I can plug any radio in any room I want and have access to that antenna from the nearest phone Jack!
As far as volume, I am using an output transformer and speaker and feel that the volume would be sufficient if I had better reception. I’m going to switch over to the Dell computer supply as it seems to have less noise and hash. Appears like getting the 3 tuning caps aligned/synchronized is being a problem, sensitivity drops way off to the point that there is hardly any background noise at one end of the dial compared to the other. Using my signal generator, synchronization is iffy as I can hear it over a wide range of rotation, no real peak. I have seen a video on YouTube of a 35 and the gentleman’s set receives pretty well. AM in my area isn’t great but I’m in PA and received a station in NC one night although weak, yet a station about 50 miles from me is almost nonexistent even though it comes in loud and clear on other radios. I thought about buying a set of 01s for it even though the ones I have test good. Getting to the point of putting crazy money into it! I’ll see after switching out power supplies.
