About as good as one can expect from a modern GZ34. They are all pretty crummy compared to English, Dutch, German, Japanese & USA made rectifiers.

These are a good, and over the last few years, much improved 5AR4. In 2005 or 2007 I wouldn't have touched one these with a 10 foot pole. But my recent (past 3 years) experience with them has turned me around on the subject, and I am NOT, and have never been a fan of Chinese tubes. It has nothing to do with China or the people or govt of China or any of that crap - it has to do with the way Chinese OEM manufacturing works.Cheap greedy investors or business owners in the U.S. contract production runs of the cheapest crap possible, and these Chinese factories are happy to oblige them.They don't care about the end user (us) because we aren't their customers - the greedy, irresponsible slags in the US or UK are. It doesn't mean that Chinese factories cant make the finest tubes known to man (without magical gnomes or secret "lost tube-making knowledge",the subject of another rant some other time) , it just means they aren't being paid to do so, and they aren't going to improve their products for the sake of pride, or reputation. Its a scurrilous business model which you've probably guessed I have no respect for at all. Now, when a company like Groove Tubes or Tube Amp Doctor forks over the money for a premium product, they and we, get one. The Groove tube 6L6-GE and EL34-M are good examples.The TAD 6V6GT and 6L6WGC short bottle black-plate are excellent tubes, or the TAD 6L6GC-STR tall bottle . Thats because they are concerned about delivering a high-grade tube produce (for which they charge premium prices).Groove tube now distribute and brand this 5AR4
(they didn't a while back when quality was bad - and that's probably why its gotten better).

Extremely low quality. I tried using one of these in a power amp I made because I thought it wouldn't matter what kind of tube I used in the power supply, and at the time this one was about $5 cheaper than the JJ tube. It only held up to regular use for about a month or two, then developed an internal short. It's a good thing I'd chosen a conservative value for the fuse, or it would have destroyed a very expensive power transformer. The JJ tube I replaced it with has held up great for the past two years, so lesson learned I guess.
