These used a lot of filament current, not like later miniature tubes. They had a UV(UX)200 tube for RF detections that worked better as a grid leak detector, I think because of less cutoff voltage needed as a detector. The A series used a better getter and lower current filament ( one or both? ) but still used a lot of filament current. Dwight
