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. The build.   ✿ RESTORATION BUILDING BLOCKS: A series of videos showing detailed steps used the restoration process of tube equipment:    • How to safely check the Power Transformer ...   ✿ HowTo's: Various videos on some simple techniques and projects:    • Extend tube radio FM band above 100MHz wit...   ✿ DIY CAPACITOR LEAKAGE TESTER PROJECT: One of the most viewed projects on my channel, with full design description and build instructions.    • Capacitor leakage tester design & build DI...   ✿ DIY TUBE TESTER PROJECT: Complete design description and build instructions for this really handy device.    • DIY Tube Tester. Working on Power Supply o...   ●●●● Plus full Playlists on some other completed restoration projects on this Channel ●●●●   📻 PHILIPS BX750A:    • Philips BX750A tube radio restoration - Pa...   📻 TELEFUNKEN OPUS 2114:    • Telefunken Opus 2114 stereo tube radio res...   📻 SABA UW-175-Z 3D:    • Saba UW 175-Z 3D tube radio restoration - ...   📻 GRUNDIG 1070:    • Grundig 1070 tube radio restoration - Part...   📻 SCHAUB-LORENZ GOLDY 58 type 3020:    • Schaub-Lorenz Goldy 58 type 3020 tube radi...   📻 BUSH VHF64:    • Bush VHF64 tube radio restoration - Part 1...   📻 GRUNDIG 3060A:    • Grundig 3060a tube radio restoration - Par...   📻 TELEFUNKEN OPERETTE 8:    • Telefunken Operette 8 tube radio restorati...   📻 GRAETZ SUPER 171W:    • Graetz Super 171W tube radio restoration -...   📻 LOEWE-OPTA MAGNET 3737W:    • Loewe-Opta Magnet 3737W tube radio restora...   📻 BRAUN ATELIER 3:    • Braun Atelier 3   📻 LOEWE-OPTA TRUXA STEREO 4741W:    • Loewe-Opta Truxa Stereo 4741W   📻 GRAETZ COMEDIA 616:    • Graetz Comedia 616 tube radio restoration ...   📻 SABA FREIBURG W2:    • Saba Freiburg W2 (WII) restoration   📻 GRAETZ MUSICA 4R417:    • Graetz Musica 4R417 restoration
