2x BLF188XR Amp with WATERCOOLING (Part-2)

Part-1: manufacturing of the water cooling
Part-2: PCB assembly and pre testing
Part-3: Final assembly and maximum power operation
Part-4: (coming soon ...) quality measurements
This is the second part of the construction of a 2xBLF188XR short wave amplifier. It shows PCB assembly and the functional testing of the boards.

    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
