Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on https://www.pcbway.com/ ➠ ➠ ➠ These German tube radios were designed with sound quality in mind, and the way they achieved that is really astounding. That's what I want to go into in this video. The preamp, as simple as it is, is surrounded by a really complex tone shaping network that is a work of art, both in its complexity, and ultimate result. I hope you enjoy the series, and invite you to comment. Errata: The pin 1 used as a convenient solder tag is actually on the socket used as the interconnect for the tone buttons, and not on the EL84 socket as erroneously mentioned in the video. 🎥 Other videos in this series: ■ Back to Basics 1 - Tube Radio Anatomy: • The Parts That Make Up a Tube Radio - Tube... ■ Back to Basics 2 - Tube Radio Anatomy: • Checking the Power Supply - Tube Radio Res... ■ Back to Basics 3 - Follow the B+: • How to Check the B+ Safely - Tube Radio Re... ■ Back to Basics 4 - Testing the power output: • How To Check the Power Amp Stage - Tube Ra... ■ Back to Basics 5 - How to safely test the output tube: • How to safely test the output tube - Tube ... 🙏 Want to support the channel? ●●●●●● / mcaldeira https://paypal.me/macaldeira #tuberadios #antiqueradio #radiorestoration ●●●● HUNDREDS OF OTHER VIDEOS TO CHOOSE FROM ●●●● ✿ DIY TEST GEAR: The title says it all: • Zener Diode Tester - Part 1.
