¿Válvulas en 2026? Por qué este Receptor sigue siendo Imbatible.

Can you hear the world with just one tube? 📻 We analyze the Regenerative Receiver with the 6AK5! There's hardly been a video this week due to exhaustion, but tinkering got the better of me. I started playing around in the workshop with some old tubes and ended up rescuing and improving a circuit that's pure magic from the radio of yesteryear: the regenerative receiver. In this video, we'll break down the operation of a miniature pentode, the 6AK5, and how to take advantage of its grids to achieve incredible sensitivity. We'll cover everything from the mathematical calculations for adapting the 6.3V filaments to a 12V source to the technical analysis of cathode-coupled positive feedback (Hartley type). In this video, you'll learn: ✅ How to calculate the filament drop resistance ($$R = V/I$$). ✅ The operation of the "tank circuit" and frequency selection. ✅ The secret to the "sweet spot" in receiver oscillation. ✅ How to build a homemade shunt coil on PVC. This is an ideal project for valve enthusiasts, those who enjoy tinkering with circuits, and technical amateur radio enthusiasts. If you like experimenting with circuits that seem like magic, this video is for you! 🛠️ Materials used: 6AK5 Pentode Valve (or similar such as 6AU6, 12AU7). 475pF tandem variable capacitor. Ceramic capacitors: 30pF, 100pF, and 10nF. Resistors: 1MΩ and 32Ω (2W). 10KΩ potentiometer. 220V to 12V transformer (300mA). Coil: 110 turns of 0.3mm wire on 20mm PVC (tap at 10 turns). 🚀 Want to support the channel? If you like what I do and want to help us keep experimenting, you can join as a Premium Member.
