Yes. A bit, not much movement of the shadow has been achieved moving the lamp. Also with the current lamp position the lighted segment is very symmetrical and is dead in the middle of the screen, while if moved it goes left-right.
At this point I am more interested in the sensitivity and the current supplied by the input tubes.
I probably need to look at the AVC voltage from the detector tube 37. Don't know the exact range.
The AVC voltage reaches -4.5V, right where the 100K resistor from the detector, the #50, meets the volume pot and the other resistors.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
