After the tube warms up, be sure to reset the line voltage to the line test on the meter. If the line voltage setting is low, all the short lamps will be dim.
Hi Greg the line test on the meter is right on it, it appears that it does on few 5Y3 after it warms however if I compare with my 6000 with any tubes it already looks way dimmer, I know there is 5 Ceramic Capacitors and resistor at the Neon bulb but I have never found that need to change those.
