Recommended tubes for ASL Hurricanes?

Tony, Thank you for you input. I am going to try the EAT's. I'm also going to replace the 6SN7's as recommended by Rwd and Jeff. I'm not sure if I'll go with the Tung Sol or the less $ Ken-Rads. I'll do some price shopping. Knowing me, I'll probably go with the more expensive ones. But, I don't know. I've got to continue to educate myself, as I am new to tubes. New - and loving it! Lots to learn and experiment with. I'm even considering having the amps "Extreme'd" by ? - Who is that that does the Extreme mod? Great Northern? Does anyone have any input on the "Extreme" modifications?

Rwd, Jeff and Scaena - I had written a thank you to you all previously, but I guess it never posted! At any rate, I thank you all for taking the time to share your knowledge with me.
