On the left the variometer with its white and blue coloured capacitor, below the variometer, antenna tuning (with fine tuning). In front of the tubes are the wavelength switch and a position switch for variometer or antenna tuning. On the right a selector switch for the feedback coil with underneath it the control knob for the feedback coil. Behind the four tubes from left to right, grid leak resistance, inductor and grid leak capacitor. The knob in the middle operates the filament rheostat.
