Warning! BS170 different pin layouts

[Jan PA3GGZ]

During the optimization of the harmonic suppression I blew up the BS170’s. I ordered new ones (luckily 6 pcs!) from a local webshop. After careful installation I had a shortage on 12V. Testing the new BS170’s I discovered that the pinout was opposite to the delivered ones in the kit. After soldering the next 3 ones everything worked again. On the internet I found different pin layouts for BS170. Happy with my cheap Chinese component tester.
