QRO Section...

This section is about building Power Amplifiers and related circuits...

- For everything you do, there is a "first-time"...
This is my first homebrew amplifier... Pictures only...

-The Tube Simulator.
Everyone involved in amplifier building knows how difficult it can be, to get the tankcircuit up to speed, and all sorts of "gizmoes" are pressed into service, to simulate the tube under load conditions. This construction makes it all; just dial in the calculated load-impedance, and the tube anode-capacity including a few ekstra pF to allow for strays, and connect it in the amplifier under construction.

-Triode Bias Board.
This construction is "nicked" from the webpage of DL4MEA, and refined somewhat. I made 2 of these boards, and they are installed in the HF amplifier build by OZ2CDJ, and the 50 MHz amplifier by OZ1DPR.

-50 & 144 MHz GS-31b Amplifier.
Construction of a dualband amplifier based on the YU1AW -GS-31b design.
