You could also take voltage from the cathode bias resistor of the output tube, to power an LED through a series limiting resistor. You may have to increase the value of the cathode bias resistor to make up for the current going through the LED, but it's already DC and will only cost you two resistors and an LED.

I like the neon idea a bit better though.
