Adrian,

Are any of those new tubes besides the Chinese tubes are single plated?  I have bought some very nice 2A3 and 6A3 double plated from 1942 and 1944 and it will give me an ability to see what is going on with vintage tubes.

I was not pleased with advertised vs. actual measurement of those tubes, even those the tubes I got were “new”. The most interest probably shell be belong the single plated tubes but they are very pricy, more expensive then the new production of the tubes. The good part is that with the new production it is possible to have assured and stable measurement of the tubes and the only concern would be this one:

There is something else.  If you look at the Srajan Ebaen’s pictures:

then you will see something that really makes me conserved. Srajan shoots it for the same of sexy look and he does not understand it but is anything in there that make you nervous? Look at the second image from the bottom where the amp is shot in dark. The blue light radiated from the sake around the filaments is OK in DHT. If the covers around cathodes have some hole then the projection of the whole to the glass might also pick up some blue light – that is normal as well. However if the whole balloon on the perimeter of the glass turns bleu then it is a very high evidence that the tube is filled with crap gas and shell be conceded faulty.  If I paid money for the blue aura tube I would return it and would ask for refund.

BTW, what you will be commenting on your new tubes then can you for me to  pay less attention to their bass and more pay attention to  texture and tone in the upper region?
