I think these amps sound the best with the Sylvania 6CA7 output tubes they came with when they were new. Groove Tubes are simply hand-selected and graded Russian, Chinese and Slovakian (typically) EL34 types.
While EL34 tubes work fine, they are NOT an exact replacement for an American 6CA7.
As you are no doubt aware, finding 6CA7 tubes has become much more difficult and much more expensive in the last few years!
