Description

Dual balanced amplifier: single cathode and space charge grid, dual control grid and anode; thoriated tungsten filament cathode. The tube was intended as electrometer amplifier working in a Wheatstone bridge circuit, given in the data sheet.

Typical operating values:

  • 6 V anode voltage
  • 20 uA anode current
  • 5 V space grid voltage
  • -3.5 V control grid voltage
  • 5 x 10exp-15 A grid current
  • 1.2 amplification factor

5764 is quite similar to 5760 / FP54 with higher electrode assembly and approximately doubled electrode surface
