I am running a pair of 6SL7s (preamp and phase inverter) and a 6SN7 (power output) on my Vox Lil' Night Train. Not only does it work fine but sounds great. I am not able to use the cover, had to remove all of the tube retainers, had to spin the spring holders 180 degrees, and use three 6SN7 to 12AU7 adapters. (noval to octal)
V1= 6SL7GT, V2=6SL7GT, V3=6SN7GT
V1= 6SL7GT, V2=6SL7GT, V3=6SN7GT
