Emission Labs 300B

Selling four (4) pairs of Emission Labs 300B tubes! I could talk about them, or a quick Google search will point you in the direction of myriad reviews effusing praise for these silky smooth little wonders. I purchased a used amp two weeks ago off Agon and it came with these babies installed. They sound great, but I plan to upgrade to the 300B XLS tubes. Can't do that till I sell these! I asked the seller how many hours he thinks are on them, and he said probably around 400-500 hrs. Usage aside, they are in pristine condition, and they sound absolutely fantastic. This is my first foray with 300Bs, and I am confident in saying I am 300B for life! I would like to sell these for $250 a pair, which I think is an exceptionally reasonable price. $1,000 for four (4) pairs. They go for $662 a pair new ($2,648 for 4 pairs).
