It is too bad that you can't e-mail other Audiogon members anymore. My old friend Trelja could tell you about biasing EL-34s in a Jadis Orchestra Reference. BTW he did the same thing but swapped out the then standard KT-90s and loved the improvement.
I bought a used DA-60 with a mixed bunch of shot EL-34s in it and went the opposite way and put in the GL KT-88s which I though were much much better. It is time to retube and since I like a "big" sound I think I will try the GL KT-77s.
