You inspired me today Dave. I have not listened to the Hawk, in awhile. I'm playing Coleman Hawkins encounter's Ben Webster right now. I'll dig out some Duke later today!
Yes, I think you will enjoy the Mullard E188CC/7308's very much. I do have the Edi with Tung's in, you are running right now...and no hurry to go back to the Mull's. You know, they are just that good! However, my favorite combo is these Mull's with the Telefunken 6922/E88CC for inverter's/yes expensive....but good for probably 8500 to 10000 hrs....so worth every penny.
Two trustworthy sources for the Mull's:

Dollar for dollar.....least expensive System upgrades one can do.
I'm sticking with the reissue Tung-Sol's/KT66's....they are so exquisite and malleable.....to influence with the best ever made and musical.....input/6922 tubes.
