• Notes

• The detector working on the bottom bend principle combines the high sensitivity of the SG valve with the lower impedance associated with a pentode. This is achieved by connecting what is normally the control grid to an HT tapping at about 60 volts positive and using the screening grid for the HT signal input. The space charge in the valve is much reduced, resulting in a lower working impedance, and only quite a modest anode voltage is required. The selectivity is above average; this may be due in a small measure to the reverse feedback of the detector being less than that due to a three-electrode valve.

  A neon tube is used as a surge buffer.
