How about these? https://www.ebay.com/itm/401750188937 Images show genuine packaging. |
| HB9EVI:
it LOOKS genuine - if it is, you have to take a risk. I'll give it a try for that price. |

Would like an RF power JFET preferably GaAs or HEMT for class A audio. Perhaps also for wifi amplification. There are lots of soviet transistors, those seem authentic. Has anybody tried those? |

I know they counterfeit 2N3904s and 2N3055s so they will counterfeit anything and expensive parts like power RF transistors are a prime target. |
