We had a mains spike/glitch because of rain

The 150W linear blew the gates on the MRF9180 in my Chinese board, lucky I have a complete spare linear.
I replaced the MosFet with one from Aliexpress for €9.19
It will bias up perfect, drive it with RF as normal and it consumes 8A at 26V as normal at 96.8.mhz...
Everything looks Normal

But... the RF output is only 20W
![Confused :?](./images/smilies/icon_e_confused.gif)
Looks like it could be a fake, I bought 3... all are the same

Even the original faulty one I took out will give me 50W if I drive it very hard, so it must be bad Aliexpress MRF9180's
This is one of my Linears
