Articles and helpful comments appear everywhere about reducing heat in power transformers, or increasing transformer life, by changing from vacuum tubes to solid state rectifiers. Most of the articles and helpful suggestions make some very silly statements about heat, such as "the power transformer is weak. Changing to solid state removes 10 watts of heat from the weak Heathkit power transformer, and extends transformer life".
It's not that I would absolutely need one! This new amplifer must have at least one technical advantage over plain simple common traditional amplifiers: Either it must be ultra low cost along with respectable performance, or it might be extremely small and lightweight, extremely efficient, or anything else like that. It should be an interesting amplifier, not just a brute force tool to get high RF power. I warmly welcome contributions!
For all you tube lovers of the world! Single Ended "Universal" replacement watts Push-Pull "Universal" replacement watts.
QRZ Forums. Most of the build instructions for homebrewing of an amplifier tube type include some rare out of reach transformer. My question is
Transformers are components used in a large number of radio projects, and represent a significant percentage of the cost of building. Since they can usually be reused in one form or another, I salvage most of the power transformers I get my hands on. The weight of a power transformer holds a clue to its power handling capability.
We know way too little about this subject but hopefully [Bob4analog] helped us learn a little bit more this time around. This is an evolving design and the two videos after the break show two different iterations. In standby, the amp sits at volts, warming the filament before the unit is switched on. Did I also see a Kenwood TS?
