VTL with KT120 tubes


I know VTL would recommend against it, but is anyone aware of someone using Tung-Sol KT120 tubes in a VTL Siegfried II or S-400 II amplifier? Results?

They would tell you the heater windings in the transformers are inadequate and might possibly damage the transformers.  So, no, not me.  But the KT90 designs of VTL and Manley, on the other hand, are begging to be run with KT120s.
