CHINESE tubes?

I have several drawers, (hundreds and hundreds of tubes) full of tubes. Both NOS and new production. I have found the new production Shuguang and Psvane to be as good, if not sometimes better, (depends on the circuit) than any of my NOS tubes from Mullard, Amperex, Telefunken, Siemens, etc.

So saying "all" of the Chinese tubes are bad, it just wrong.

One has to be careful with broad brush statements when their are so many variables at play. I use a mix of NOS & Chinese tubes in my systems with excellent success. The NOS 845's & 300B's were just a little too expensive for my budget. I used the Shuguang ,Nature series & 300B Treasure Series in my Cary 211 amps & I am very happy with the sound as well as the reliability. I had the 300B's cryo treated which kicked their performance up another notch.

That is a totally inaccurate statement. Vac , and many others have been using 
dependable matched tubes for years Shugaung has been making tubes since 1958. They have had old RCA and Tungsol original machines in there from way back and have made new machines similar.  Their El34, Kt88 Kt120 
power tubes all very dependable . And small signal tubes a lot direct American copies .Old 60s50s tubes tubes better for various reasons mainly 
a bit better materials and  much closer inspection per 100, hoot 1,000s
if you want top tubes the a Black treasures are very good quality and highly musical.  They are a bit $$ pricy  but are superior for power tubes no Russion tube is better.  And if you buy from them on eBay you get a full 12 month warranty . You will not top that.

Mofi,  If you're not going to use those NOS tubes, why don't you put them up for sale at a good price and give some of the tube newbies a chance to compare them with the Chinese tubes.

There is no way that I will buy an Ongako and plug in Chinese 211
