the yellow trimmers were band new when i built it a year or 2 ago. they have hardly been turned at all. i think ill bypass the 1w input section and just drive it at 5w for now.

I'd probably recommend checking the condition of the yellow trimmer caps, even better would be to replace them if they have been subjected to many turns. Also they seem to attract dust and dirty easily which can be dragged inside and damage the thin Polymer film separating the plates and cause a short.
