Looks like a KF8OD amp to me. Nice assembly unit.

yes, I got the idea to use two BLF188XR after watching your videos. Should be rugged enough to hold a lifetime.

Hi what cooler are you using to cool the water. I did not see it in the videos. 73 Jens DF5HC

Kurt vielen Dank für Ihr Video zu dem Thema ein Solid-State-Leistungsverstärker zu bauen. Glauben Sie, dass der Transformator 1: 9 mit zwei Transistoren ist die beste? Und die letzte Frage. Was Sie ein Ferrit verwenden? Vielen Dank.

Danke nowember711, ich verwende den Laird 28B1020-100. Dieser Ferrit ist sehr billig und funktioniert sehr gut. Mit 1:9 kannst du eine Ausgangsleistung von 1200 Watt machen. Die zwei Transistoren können natürlich mehr. Mit 1:16 könnte man 1800 Watt machen. Da wir in DL ein Limit von 750 W haben, ist 1:9 für mich gut, die Linearität ist optimal.

Hi Harry, what is the size of the copper plate that you're using?I've found 10mm copper near me, but not more than that, so will use that.NunoCT2IRY

10mm is absolutely fine, you do not need more. vy 73
