I looked into the cryo before purchasing my Teles. I didn't go for that option. Someone put it well saying that the mechanical stresses you will be putting on the tubes under during such an intensive process might out weight any benefit the process will induce. That made sense to me. Considering all of the various materials in the tubes as well, since different materials expand and contract at different rates under these extreme conditions I was afraid that the structural integrity of the tube might be compromised during the cryo. This is evident in in rbs experiences as well, I would say opt out of the cryo. 

+1. That flexing due to extreme cooling and heating, may weaken the vacuum seal. On these tubes - a loss of the vacuum kills the tube (this can be seen as a white frosting where the getter flashing used to be - as it's purpose is to absorb stray gases in the vacuum).

Just had 24 of these delivered!

What a score! All '74 Silver Shield SWGPs? These are very hard to find, but a little easier then the '75. The supply of '70s 6n23p SWGP have really dried up. Getting harder to find.

A world class tube.

You mean $850 a pair is unreasonable?!

Oh but do they have sexy curved waists? Lol

I'm thinking the $235 I paid for a single was a bargain! Cough...cough...

 

[Tuco1965]

That must be some pretty fancy fire in those bottles for those prices.

Yes! Tube World has one for $99 branded Valvo curved d getter 1960. Very tempting... I hear the 6dj8 is better then the 6922...but uber microphonic

Edit - Look at what you made me do! Just bought this on Ebay! http://www.ebay.com/itm/Good-Pinched-Waist-Amperex-Holland-6DJ8-Vacuum-Tube-1957-Date-/161299039496?pt=Vintage_Electronics_R2&hash=item258e2c0508

Edit2- Scratch that on the Tube World Valvo - Not a Pinched Waist. Oh well I have a 6dj8 coming.
