Shows the oscillator isn't working. The tube should be OK per your tester. Carefully check the wiring against the schematic of a typical 6A8 oscillator/mixer in the article referenced. Also check continuity of each winding on each of the three exposed coils, just to see that no wires are broken. I have a hunch they aren't, since the radio worked weakly in the beginning. I'm thinking there's a wiring error.
Here's where signal injection would come in handy, working back from the first audio tube.
