Jj Electronics T-12At7-Jj Vacuum Tube Ecc81 Electric Guitar Power Amplifier

Q: Will these make my 15 watt Vox Night Train sound much better?

Depends upon the condition of the existing valves in your amplifier. If the valves are well used and near the end of their life there ought to be a significant improvement. If they are new and the original valves supplied as stock you might perceive there to be some improvement but I would doubt that it would transform the amp in such a way it could be described as being "much better".
