www.amusicdirect.com is carrying a line of newly manufactured tubes called EAT Cool. Strange name huh. They are supposed to be good for 10,000 hours and supposedly blow the dorrs off any NOS. But for the price of $225.00 each they had better. I remember seeing a replacement for the 12ax7 and 6dj8. They also have a Genalex KT-88, $105.00 a pair, that look to be newly manufactured.
