HOW TO TUNE UP THE AMERITRON AL 811H 

Great video Roger- Love your station on QRZ.. W8JI just posted a video on a diode short that causes the grid current to stay up when not transmitting. Not sure if your grid meter is just off or if it could be that diode- might be worth checking out. 73s W5YAK

Where did you get your pulsar from? I have the same amp and would like to tune it with a pulsar also.
