Re: Tube recommendations for 2010 Dual Rec?\
I think of the modern tubes available, the new Tung Sol's have the most attitude. They just seem to be the hot tube right now. There are some NOS tubes that are fantastic, but with a very modern amp like the dual rec and the unique tone it produces, I'm not sure NOS glass would yield the best results for the money.
Also, maybe just some of the 5th Gen Chinese tubes. High gain, low noise and great reliability. Lots of people, amp builders and players swear by them.
