Cómo Armar un AMPLIFICADOR PROFESIONAL Desde Cero (Curso Completo)

Welcome to a new video on Desvare 5070! Today I bring you the definitive, step-by-step guide on how to build a professional, heavy-duty audio amplifier from scratch. If you wanted to learn about power electronics and see how to create something designed to last over 10 years under heavy use, you've come to the right place. Don't worry, I'm nervous, but I'll explain every detail, holding nothing back. In this super masterclass of almost an hour, you'll learn how to build the Bakelite enclosure, wind the primary and secondary transformers, prepare the heatsinks, make a high-amperage rectifier bridge, and install a balanced RAM audio board with 28 power transistors (2SC5200 and 2SA1943). All with reinforced solid copper traces to prevent any current leakage. ⏱️ VIDEO CHAPTERS (Index for YouTube): 0:00 - Fabrication of the bakelite/fiberglass enclosure for the transformer. 4:10 - Beginning the winding (Copper #13 and #14) and separation with fiberglass. 11:56 - Assembly of the square iron core and application of anti-corrosive paint. 16:32 - Measuring, drilling, and polishing the aluminum heat sinks. 21:04 - Cutting the bakelite and soldering the transistor bases. 24:20 - Creating the filter bank (15,000 µF) and rectification with 20 diodes. 29:32 - How to measure and assemble transistors (2SC5200 and 2SA1943) with insulators. 31:52 - Installing emitter resistors (0.47 ohms) in parallel. 36:20 - Connecting the RAM audio card with balanced audio. 40:56 - Wiring neutral, voltages, protection fuses, and power. 45:45 - Noise reduction trick (33 ohm resistor and 105J capacitor). 47:25 - Amplifier 100% complete and final details. 👇 Key materials and tools used in this project: #13 and #14 enamelled copper wire (Transformer) #8 bare copper wire (Track reinforcement) 28 Power transistors (14 x 2SC5200 and 14 x 2SA1943) 4 x 15,000 microfarad x 100V capacitors 20 x 6 Amp diodes Balanced RAM audio board #25 fiberboard/Bakelite 60/40 solder If this tutorial was helpful for your electronics projects, don't forget to give it a thumbs up, share it with other audio enthusiasts, and subscribe to the channel.
