Tube replacement for Dynaco ST 70

I just purchased a highly modified Dynaco St 70 and it came with EH EL 34 and I would lke to replace them since I feel they are a liitle thin and veiled on the upper midrange and lower treble regions where the voices are produced. Any suggestions on replaceing them with tubes that will open up and unveil the voices. I can uses 6L6 or KT 66.

I own one of Will Vincent "Audiospec" Stereo 70's.
Recently upgraded the output tubes to the Gold Lion KT66
and have not looked at other EL34 tubes. The soundstage just opened up. With this amp the improvement is huge.
All the best....

Cavy,
Will Vincent recommends 1.40mV DC meter for KT66 and EL34 tubes. Just read your post today. Sorry for the late respond.
