Alternate tubes

Has anyone here used a 6DZ7 (or the real rare 6DY7) to build an 18watter? It has two 6BQ5 equivalent assemblies in one envelope with a shared kathode. Did it sound OK? I've been thinking of making one using a 5E3 chassis. It would free up a socket hole so I could make a two channel amp. I have a bunch of the 6DZ7's.

Going by the spec sheets, it looks like a 6DZ7 is more like a pair of 7189As, as each pentode inside can take higher voltage and dissipate slightly more power than a regular EL84. A pair of these would probably also make for a great 36W.
