It is unlikely the balun is “breaking down”. It’s a current balun - #43 ferrite

That's a common mode choke, and #43 is a terrible material for the HF
bands. See my "cookbook" at k9yc.com/publish.htm as well as the Ham's
RFI tutorial, which explains things conceptually.
"handle a kW," perhaps, but only because it's also unlikely to be doing
anything useful. :)
