Wanted to consolidate my threads, get rid of the old photos and clutter, so here is the new one.  Review my old posts for previous tubes sold.
 
Same with the other threads, will note the tubes were tested with a TV7B/U that was calibrated March of 2015.  If you wish to see photos of individual test results I am able to do so but please understand work keeps me very busy and it may take a day or two to retest them and get you the photos, will place items on hold in interim.
 
All tubes are used, I try to track hours as possible but for me music is listening not analytically evaluating, so I estimate very high on hours to error on the side of caution.  These tubes were used in either a WA22 or Decware Taboo Mk3.
 
NOTE:  Buyer is responsible for providing the fee noted for the cost of the tube, this cost includes shipping but not the PayPal fee.  Per forum rules Gift should not be used but we can discuss options if requested privately.  
 
Items ship CONUS or Local Pickup in Las Vegas only.  I've learned customs is a pain and don't have the time at the moment, apologies international folks.

Not much interest (probably the price and I understand) and got another amp on the way so will hang on to them for now.  Thanks everyone who I have dealt with recently.
