KX1 switches off when antenna connector shorted

[NA7U Shack]

Is it normal for the KX1 to shut off if it sees a short across the BNC
connector (no RF applied)? I'm trying to use a 4:1 Guanella balun (which
looks like an electrical short) but the KX1 shuts off if it's in line. I
tested this behavior by simply shorting the BNC, also.

Casey,

That can happen if C44 fails shorted.  Turn the KX1 on and measure the
voltage at the center of the BNC jack.  If it is not zero, replace C44.

Oddly enough I tried a different power supply and it was OK. Then I
tried again the previous PS and it was OK. ?? I will check C44, however.
