new tubes in a Einstein. KT77's ?

[tripstan]

I going to retube a 100 watt Einstein. It currently has Ruby 34's in it. What are you guys using and why. I like the EL34's but kinda want to try something else.
I also see Peter recommending kt77's in VH4. Would you also recommend kt77's in a Einstein?

I personally like the KT77's better in Einstien than vh4 and Hagen. I stick with EL34's in them and 77's with Einstein.

Thanks, what do you bias them at?

35 mA as per Peter's recommendation.
