¿Cómo funciona un amplificador a tubos de vacío (Válvulas)?
I have published a video on Youtube explaining how a tube or tube amplifier works, illustrating how it works
I have posted a video on Youtube explaining how a tube amp works or valves, illustrating the operation of each of the stages in the simplest possible way. This is a beautiful 1950s Pathfinder amp that I got my hands on recently. Like most amplifiers, its design is simple but functional, as well as PERFECT for a didactic explanation of its operation.

I leave you with the video, in it I have published the schematic diagram of the circuit with all its details, from the rectifier to the power amplification stage. I hope it is to your liking and usefulness.
Errata: En el video presento al rectificador de la fuente de poder como un rectificador de media onda, siendo un rectificador de onda completa. Gracias al amigo Taoiste, que me hizo notar que se trata de un doble diodo.
En este mismo blog he publicado otro artículo acerca de cómo convertir uno de estos amplificadores de propósito general o incluso una radio a tubos, en un excelente amplificador de guitarra eléctrica. Aquí les dejo un vínculo:
