It's not unusual for something that is out of alignment to briefly pass a signal as it starts up while voltages and things are cold, but stop as it gets into normal ranges.
Thus alignment is done when the set is warm.

HELL, all my sets that are able to tune in stuff take 60-90 seconds before the can tune correctly, then they run OK for hours, what you see in the first few moments does not mean anything.

Oh I understand what you’re saying but this is when it was already warmed not just turning on so I don’t know I have new .001 caps maybe I’ll try one in L4 and see what happens. If that don’t work then maybe I’ll disconnect L4 and check resistance and see what comes up.
