Jon,
Had a 412 on the output of a 100 watt transceiver, worked fine for 3 ssb cq
calls and poofed midway thru the second CW cq call. Never got hot, not in
service long enough, VSWR was 1.2:1 prior to failure so I was kind of miffed.
Sent it back to ICE and they PROMPTLY replaced it, I have not yet put the
replacement in service. Total time in service for the first one was < 5 min.
