I'm not as familiar with the recent marks of this amp, but the French Jadis website says that it was originally designed for use with EL-34s, but the 6550s, even plain old GEs, sounded better. I would think you'd have to have someone change the internal bias if you want to do this, as the Defys weren't self-biasing like the JA 30s, 80s and 200s. Finally, in my view the Defy was always tubby and over-ripe in the bass, even with 6550s; I would expect the performance in that area with EL-34s to be even worse, although the midrange should be better. If you don't run it full-range, that might not be a problem.
Jadis Defy 7 info-EL34s??
Does anyone know if a Defy 7, late version Blue Caps in the rear, can be run with El34s?? According to the owner, it came stock with 6550s. In my Jadis sales lit, it has them pictured with El34s.
Id prefer the run them with El34s, as I like the sound of that tube, have many on hand, and they tend to be cheaper than the Kt88s and 6550.
thanks
