Gone are the days when I used to service TV sets and could easily obtain the occasional BF981 from a scrap tuner.
These days I obtain the occasional modern miniature tuners with very tiny SMD MOSFETs with no markings, The Peak/Atlas component analyser will read it as a MOSFET with the 3rd test lead connected to either gate in turn, but it can't tell which way round the d & s pins are or which gate is which.
Anyone know of a way to determine these finer points?
TIA.
