I plan to lay in a supply of replacement tubes and it seems that there are several options. One is "cryogenically" treated tubes - are they worth the premium? I ask because I am a tube novice and I don't know if I should just buy the $5 used tubes or the $20 cryo treated new guys.

Good luck other waiters

Hi, I think cryo'ed matched pairs would be worth the few extra. What is your source for cryoed toobs? Tube world did not offer cryo I think, maybe I missed something. Like you I have been burning in my W1000's while away at work for at least 200 hrs now. Am I done?

My yamy is due any day now!

The source for the cryo'ed tubes was indeed Tubeworld. I have not purchased any tubes, yet, but I have talked via email with them and the cryo'ed tubes came up. I can't remember if they are listed on the web page or not.

My amp is also supposed to arrive soon - this week was forecast. Good luck!

So you got the Northern Electric 408a's not the Western. Do you know if there is a significant sonic signature differance between the two?

Thanks...

I already have extra WE tubes and some GE tubes now I will have NE tubes that are cryo'ed. I really have not notice any difference between the regular WE and GE tubes. The thing that made me think that something got better is the IeGO PC that I place on one of the Yamamoto's. This made me think it open up even more of the SEP sound that is possible. Once I put the tubes in the one with the IeGO cable I will also put in a cryo'ed hi-fi fuse and see what happens.

I had one tube that seem to get a little microphonic on me and the replacement is better. I also am using to Deoxit Gold on the plugs.

Brendon of Tube World says they sound the same. BTW, there was one pair left after Slwiser practically cleaned out the entire supply. but I bought it
