Diamonddude18 : I can't say to be sure but my guess is these tubes would/should be checked for noise etc. after the cryo process,and do to the expense of the process I would assume ( again )theres probably a failure rate on some tubes that don't make it thru the process. A while back I had checked on the price ,if you were to send lets say a quad to have cryo'd.The cost was $10-$12 per tube.That may or may not be true now. My El34 SED can be purchased online for $75 ) aprox ) a quad. I paid $150 cryo'd ( price is with new tubes )...These are Pearl Cryo's.They were purchased at The tube depot..They have many other cryo'd tubes available. Nice people to deal with too.
