Description
This Svetlana 811A Amplifier Tube has been Tested & Guaranteed near Full Output.
I use an Ameritron 811A HF Amplifier to test these tubes.
I place the tubes one at a time in the amplifier, and check it on 40 meters with 50 watts of drive.
These tubes put out over 300 watts with 50 watts of drive, drawing 110 ma of grid current which is near full output,
and close to what I see with a new full output tube as comparison.
You may see different or better performance depending on the voltage in your amplifier.
