rectifier tube 274b 5r4gyb specs comparison

Hauntingly beautiful tone, lots of air, great layering, transparency above the rest, and just perfect extension in both the highs and lows, deep bass, palpable, lucid midrange, holographic 3D staging and imaging (like with the WA22 and Glenn OTL, the image is very life-like and out of head unreal good at times), amazing! Overall balance is great as its neither overly warm nor bright, transients and PRaT are as good as they get with tubes (like seriously, beautiful liquid transients!). As with many of the rare holy grail super tubes out there, they are nearly perfect in every way. Anyways, the sound? This is by far the best tube I have ever owned or heard. The construction is quite interesting, having the same domino plates and overall build as the Tung Sol 5998 power tubes. This is Western Electric's version of the 5U4G, with slightly different specifications, it should be fully compatible with 5U4G amps (Stratus - maybe, Woo, Decware, etc.).

Western Electric 422A (early 50's grey plate and later 60s black plate) The 2359Glenn thread also offers tube discussion throughout.Īnyways here it is! And in no particular order.ġ. To complement my review as well as to serve as a reference, the following posts/threads might be of interest. However, for the most part, their general characteristics remain pretty much the same as long as they are compatible with the amp. I have noticed that some tubes do indeed sound different on different amps, so do take that into consideration.

Most of my listening has been done on the Woo Audio amplifiers such as the WA6-SE and WA22 I have also spent quite a lot of time rolling these tubes on the custom 2359Glenn OTL amp I've been using recently. This thread will serve to put some of those ideas together.Īs many of you know, I have owned several amps that use these rectifiers and after many hours of listening, have decided to put together a comparison/guide/review thingy to help people decide what tubes they would like to use in their amps, as well as a general opinion as to their sound, performance, and how they compare to many other tubes available. I also have noticed that a general 5U4G/Rectifer tube rolling thread does not exist and impressions and recommendations are spread throughout many different threads depending on the amp. I have been wanting to create this thread for quite some time now, since I often receive PM's and questions asking for advice on tube rolling.
