Tung Sol 5881 Quad. 6L6 equivalents. Reissues, modern production. Bought as a matched quad. Less than 75 hours usage. Tested 40,39,40 and 40 on my TV-7. Minimum good for 5881 is 25 so these are testing at or close to new.
I sold the amp that uses them so no longer need these.
$50 $45 for the quad shipped CONUS.
