One thought on “Sylvania GB-6201 Gold Brand Gray Plates”
Lovely tube. Not as good as Black Plates version, which has better bass, but otherwise very similar – musical, relaxed and transparent. Sound is practically the same as Sylvania JHS 12at7, which is not surprising since Gold Brand is the same as military JHS version without the gold pins. These tubes put Telefunken ECC801S to shame! 🙂
