There are far far better options in the 5670 family. The most expensive is usually the Western Electric 396A. Cheaper alternatives are the Tung Sol 2C51, Foton 6N3P, best ones are the 50's triple mica, extremely rare. The double mica 50's Foton just as rare. For the GE 5670 sound signature, the CBS 5670. I like them way better than the GE 5670. You can do real good price/performance in the 5670.I have a pair of JAN GE 5670 tubes that I liked the sound of in my LOXJIE P20 amp and I am going to try them in my LP with an adaptor. I hope to get the clarity of the LP with the smoothness of the 5670 tubes. However, I am quite new to this whole tube rolling thing.
