This is the worst month I've ever had buying tubes
1. snagged a telefunken and mullard 12au7 on ebay. Telefunken was fine, mullard was bad. Not a big deal, got the money refunded for the mullard
2. Got a metal can 6AS7 off of the bay, says tested in the auction, seller accepts returns. Dead as a door nail. Not a problem, seller refunded money
3. Had enough of the bay and decided to order a 6AS7GA from a well known internet vendor. Tube was dead as well. RMA requested
I give up
