There has to be bad info in filament data. 24V/1A does not seem to be real for heksode.

The picture shows a rather large tube which can handle some HF/RF power. Unfortunately no data are available yet, but one can assume this hexode has double control properties to allow modulation of an HF/RF carrier.

Best Regards,
