Not too shabby!


Verified Buyer

This tube is a nice surprise. I bought it for my small single-ended amp that uses one pre-amp tube, one power tube (EL34), and one rectifier tube.

I had a nice vintage EL34 tube for it that sounded great, but recently that vintage tube finally went bad on me and since then I've been looking for a good replacement. Unfortunately, "good" vintage EL34's are priced out of sight.

I've tried a couple of other different current production EL34's in it, but they were missing some of the characteristics that I was used to hearing from the old vintage tube.

So far, and to my ear, this is the best of the current production EL34 tubes that I've tried in this little amp. I don't know that I'd call it "sensational", but it's definitely "not too shabby"!
