L3 just dropped some new WP 24UA's on my doorstep, they are now in a DTNVS housing for demo during the class. FOM's over 2300 with HALO and EBI < 1. Gotta say, these guys can make some nice tubes. I think these might be my favorite setup, since mama won't spring for GPNVG-18's. Might slap an E-COTI on with a battery pack to complement the M300W setup.
