EAR 890 and KT120


Any EAR 890 owners tried rolling KT120 in the amp?

Thanks! EAR 890 is one of my favorite tube amps. Maybe Tim de Paravicini will build something with KT120??
Can you use KT 88's in the 890? My dealer stated that the way to is with 6550WC's. What are you all using? Also, does anyone have theirs set up as mono blocks? If yes, any problems?
