ok.

The tubes sound good overall, but I was somewhat disappointed with the matching consistency and measured strength of the sets I received. On my Dan Nelson calibrated TV-7 (calibrated last month), 3 out of the 8 brand new Select EL34s measured below NOS threshold levels. Additionally, one of the matched quads measured roughly a 12% transconductance spread across the set, which was wider than I expected given the additional cost associated with purchasing matched quads versus individual tubes. That said, the tubes themselves do sound good in use, and after reorganizing the sets based on my own measurements, I was able to create one reasonably tight quad and one acceptable quad.

Shipping was problematic, as the item was left in the public hallway outside my locked office over a weekend, necessitating an extra trip to the office to keep it from being stolen. This occurred despite a call with your carrier who dutifully recorded my instructions, and put them on the package label, only to be ignored by the person who dropped the package in the hallway. Support was courteous but unable to resolve installation issues discussed in my review of the item. I am very disappointed with the entire experience and am considering other vendors for future purchases. If you would like to discuss as a kaizen, let me know. I like Apos and appreciate what you are doing, but this was not an experience that makes the customer want to come back for more.
