Linlai E 6sn7 tubes

My amp uses 4 tubes in a cascode gain-stage. I have a pair of E-6SN7s in the front slots, 1940's Ken Rad VT-231 black glass behind and a Sylvania '53 GT as the driver. It sounds fantastic. The Linlai is very transparent but the K-R is colouring the sound with its deep forward signature. I'll swap in a neutral Sylvania and hopefully the Linlai's sonics will be easily heard. That's the issue of using a multi-stage amp, the different colours of the tubes influence the sound. If I could fit 4 of these large bottles I'm sure it would sound wonderful.

My 6SN7 preamp is in the shop, so looking forward to rolling in the Linlai. 

Just contacted Viva Tubes & they informed me that, the 4 tubes I ordered will be individually boxed w/its test data. If anyone is curious. 

I should be getting my credit from them for my returned tubes any day now. Good specs, but noisy. That is why I paid a premium for Grant Fidelity tubes as they actually listen to them with headphones to weed out the noisier of the quietist tubes. Based on Jayc's recommendation, I ordered the globes.

Let's hope your system still withstands those noisy tubes - ha! 🎧🎵🔊

Since you had no issue with my China sourced tubes, you should be golden.

“Just contacted Viva Tubes & they informed me that, the 4 tubes I ordered will be individually boxed w/its test data. If anyone is curious.”

Does Viva tubes include test data for all tubes they mail out? I don’t recall if I had test data verified by any previous orders with Viva. The website says they do testing to within 5% of each tube pair. Seems reasonable. 
 

Which series of the 6SN7 did you order, E-6SN7 globe or regular 6SN7? 

Yes- to the Data, I ordered the E.
