This is my second 7HO4 chassis I’ve done. First one resurrected without too many issues. This one currently has me stumped. Radio tunes strongly until I get down to 94Mhz at which point the radio goes completely deaf. The local NPR is at 89.3 and usually the strongest signal in the area. I can just barely get it in and none of the other stations come in at all. My RF generator doesn’t even come through. Everything above 94Mhz comes in loud and clear. AT7 is brand new. Other tubes checked fine but I’m testing with a MightyMite and I know it’s lied before. Any ideas appreciated!
