Something else is awry there Michael. I have a friend with a TubeHobby IN18 that i built for him that’s been running for well over 6 years now with no issues. The only modification i ever made was putting an extra heatsink on the regulator as what was there (board plane) didn’t seem sufficient to me (just a hunch, I’m sure Jonas knew what he was doing..)....
