I bought an Avatar SE that came with NOS tubes. National Electric (Siemens) EL-34s and Mullard CV4003 (12AU7) and CV4004 (12AX7).
You might want to try the National Electric/Siemens EL-34s. Will probably cost about $250 for the set. The Mullard CV4003s will set you back about a $125 or so and will definitely add some mid-range bloom. They tend to be a little warm versus say the equivalent in Telefunkens. RCA 12AU7s (chrome domes) could be another option that will help add some bloom as well.
Be sure to get some really nice low noise tubes though. Andy at Vintage Tube Services has always done me right.
