“Good high end extension, a warm and full midrange and decent bass extension. Imaging is precise and the perceived staging is wide. What could be better?”

One thought on “Sylvania 6SN7GT black flat plates”
The Sylvania 6SN7GT black flat plates are another “Tre Fantastic” offering from Sylvania, providing a very nice warm sound, a great sound stage, and fantastic precision in instrument placing. The treble is notably sweet, and while the bass is not as tight as what you find in the “Bad Boys,” it is more rounded and natural, making it a perfect fit for systems where extra bass reinforcement is not required.
These tubes are the predecessors to the famous T-plates, featuring a foil getter on the bottom, and were produced during the late 1940s and very early 1950s. While they look very similar to Ken-Rad tubes, they feature a distinct construction difference, Sylvania plates have seven holes compared to the Ken-Rad design, which makes them very easy to identify. This is definitely a tube to have, especially since they do not currently command the crazy prices of T-Plates or VT-231 variants.
Final Verdict: Highly Recommended for those seeking a warm, natural sound with precise imaging at a more reasonable price point.
