Thanks guys.
Fjn04- My speakers are listed at 90 db into 8ohm. No detailed measurements exist that I can find so I don't know how flat that is. I'm just going to try it and see what happens. For teh record I wish Dehavilland used different tubes in their GM-70 other than the GM-70 tubes. There are just no great 12SN7 GTA's and GTB's, and I have similar feelings about the 6AU5.
