I’ve had a similar symptom on one of my sets a few years ago. I monitored the control grid voltage on the audio out put tube and found the voltage slowly creeping up after a full recap after several minutes. I disconnected the coupling cap from the previous audio stage and it still kept going up. Turned out the tube itself was bad!
