I'm running out of wild guesses. Slow onset and slow recovery seems like a thermal problem, but if the bias voltages aren't changing, what could it be?

What happens if you run it until the video disappears and then ground the collector ring with a clip lead/screwdriver? Could this be a bad ground connection charging up the second anode?
