Just when you thought this topic met a fateful end, I've attached images of an adhesive heat sink applied to the PA MOSFETs in my low band QMX.? Because the TN0110 MOSFET's have the flat side facing up, that arrangement lends itself nicely to a low-profile heat sink.? ?In addition to the self-adhesive compound, it's compressed against the MOSFETs by the quarter-twist plastic tab on the LCD display.? ?
I make no claim that it's any more effective than the existing steel washer configuration but decided to try it anyway.??
