Re: Typical KT88 impedance?
Heiko,  
 
The GEC KT88 amp design book shows an AB1 UL 100W circuit for two KT88's, using 4K for 460V B+ and 4.5K for 560V, and they also have an 8 x KT88 AB1 circuit using a 1K primary Z @ 560V B+. From this, I would say that any good 100W OT around 2K primary Z should work fine with 4 x KT88's at 460 to 600V B+.
