You could give Roger Modjeski (Music Reference) a call. He makes both single-ended and push-pull tube amps, with EL34's and other tubes.
EL34 SE as stable with complex music as EL84 PP ?
Speakers: 92db singledriver, 7 Ohm average, 4 Ohm at 60Hz
Question: Will the single ended designs (EL34 or KT150) be as stable with demanding complex music as a push pull EL84 amp?
Looking for: Ultrastable timing, high resolution, presence, openness
Possible 10 Watt amps: LEBEN CS300XS (EL84PP), Coincident Dynamo 34SE, Dennis Had inspire KT150, ifi retro STEREO 50 (EL84PP), valvet E1r (SS)
