…but it appears the difference is mainly in mechanical durability, at least according to http://www.tubes.ru/techinfo/HiFiAudio/6p14pev.html. This source lists the plain, -V and -EV versions all as 14W plate dissipation, but the suffixed tubes can tolerate higher acceleration, vibration etc. However, another source seems to list the plain 6p14p as a 12W tube.
Certainly the -EV or -ER versions will be a safer bet in the Sherwood. On the other hand, sources list the maximum plate dissipation for the 7189 as either 12W or 13.2W, so I really don't know what the minimum requirement would be.
