Practically all tubes in the Gold Brand series have earned legendary status among audiophiles. In this article, I will go into details of the brand and what makes it so special.

Sylvania introduced Gold Brand in the middle of the 1950s to compete with GE 5 Star, RCA Command, etc. Practically all companies that produced vacuum tubes had their own “Gold Brand”. For example, Mullard introduced 10M series. Philips had PQ (Premium Quality). Gold Brand tubes have been designed to work in critical industrial, military, and commercial applications. The tubes assured dependability under mechanical (500g) and thermal shock conditions (330 F and 165 C). The tubes were tested under crazy conditions to maintain electrical characteristics and reliability. As a result, tubes in Gold Brand were guaranteed to have an average life of 10,000 hours (5,000 for regular tubes)👇
