These pages will chronicle my first amplifier project. I will
discuss overall motivation & constraints, why various choices were made and the current
status of the project.
This is not a project that has a very well defined start or end ( I will
explain more a bit later). But after all, it is the journey that is most
interesting!
4-400A Tetrode HF Amplifier Project
Epilogue
Many parts of this project remain undocumented here.
Too much time has passed and my interest has moved on to other things.
However, the project was successful and the amplifier was used on the 80, 40 & 20 meter bands.
It worked well for SSB, CW, & RTTY.
