I usually ship out the item within 24 hours and was able to keep that promise most of the time.
All of my items are from non-smoking and pet-free household.
I have good feedback on head-fi: Feedback for hifidk
Around 100 positive feedback from eBay: eBay Feedback


These are Kuhl-Tubes, which means they are Cyro treated. "TubeWorld's cryogenic process takes select tubes and deep-chill anneals them for 36 hours at -193° Celcius / -320° Fahrenheit in a cryogenic chamber, producing a superior sounding vacuum tube called a Kuhl-Tube." These tubes are pretty expensive and really hard to get.

(2) 1950's Kuhl-Tubes Cyro treated 5687WB Tungsol branded Raytheon: $OLD
Tubeworld.com is selling these at $175

Price includes shipping and paypal.
