I have never heard these tubes described as warm, or full-bodied midrange. In either guitar or hi-fi amps. At least ones designed to take the EL34 as OEM. You didn't change any coupling caps or idle settings in the gain stages? Idle bias dissipation the usual 6CA7 range?
What vintage are those EH 6CA7 tubes? Be nice to pick up a few sets of them.
