The (first) non pre-production SFT25R in the F9 bin arrived today and was immediately put into my M21E (8A buck). The 3535 gasket is my own design based on the measurements of the 5050 convoy gasket. It is a resin 3d print. The SFT25R is pushed quite hard, but the temperature seems to be fine, get not really hot. I expected much more heat and thus used CPU thermal grease (8w/m k). I went with the F9 because it is the brightest flux bin with is about neutral, last pic is moonlight. As usual SFT25R is not neutral on low levels 🙂
