Re: On the subject of fake IRF510

One thing to keep in mind is. IRF-510's are actually power MOSFETs, and NOT originally designed for RF amplification. Tolerances that might be acceptable for the original intended purpose, might not be sufficient for use as RF devices, so if you get MOSFETs that are at the extremes of the tolerance levels, they might blow when used as RF devices even though they may have worked just fine in power applications. So cut-rate IRF-510's might not be "counterfeits" per se, but they may have been near the edges of their tolerances (or even somewhat out of tolerance).

The individual bought the parts on eBay, he didn't want to pay Mouser or Digikey shipping prices for such an inexpensive part:
"Instead, [Ryan] found a supplier for five of these MOSFETs for $6 shipped. This was a good deal and a bad move because those new parts were fakes. Now we have an opportunity to play spot the fake MOSFET"
The fakes were 5 for $6 shipped.
