For all.
For the same reason to all others tube lover, I pick Emission Labs (EML) 3 type tube - 300B¡B300bXLS and 2A3M for it "seems" trustworthy and reliable outlook than any anothers, especially China 300B. though it's very expensive tube.
When I use the first 300B I got, the tube base was loose,and it sounds unbalance after I burned it for 200hrs.so I tested the bias and found this tube was close to dead. so I shipped it the agency and they give me a discount to bought another one.
I still believe EML's quality untill my another 2A3M was also gutted only in a very short term burning. I found it have hums and more and more serious,and all the same, the base was loose(seems all EML tubes have base loose problems when I asked other users).so I examine the bias and found one of 2A3M was close to burned out.
I wrote to agency and tell them the problems, and they just tell me my purchase date over the guarantee date, so what they can do is give me a special discount to get another one pair.
Be careful to all tube DIY lover for my tragic experience in EML 300B.and think twice again before you pick them to home for their trustworthy outlook.....they're just like those beauty but always dangerous and let you belly up.....
