#4 level set. IC4-1 is where the signal is sampled on its way by. That to top of voltage diviers R145/R146 = 12k/18k mid-point to base of T34, Collector T34 to base T28, which shunts the LED. APparently T28's job is to turn the LED OFF.

COmpare readings to ch3 level set light circuit IC3A-1 to R143/R144 to T33 to T27
