Title: K4600 problems Post by: woodmedic on November 15, 2016, 12:52:33 pm I just capped my K4600 horizontal monitor. Before the repair it was wavy going down both sides. It resembles the hula picture on the flow chart. The motion of the waves is pretty slow. In the manual it states to check the blue lead on TR502 for B+ of 127. When I checked it was around 109V. I tried to adjust the voltage using VR501 but the pot has been glued at the factory and I could not get it to budge. Would the voltage being around 109 cause what I am seeing? What is the best way to break that VR loose?

I think this is exactly what's going on with my Jump Bug.

On my k4600 I turned the red pot a 1/4 turn now all my game boards work on it now.
