LTSpice Triode "Unknown subcircuit"

OK so you want to install a collection of tube models and their supporting symbols. Note both are provided with no warranty implied or otherwise.
.

Finally, a well thought plan to install valve models.
There are lots of results if you do a search but none of them work.
This one does, greats stuff, thank you.

There is a newer version of LTSpice XVII which is 64 bits and runs a lot faster that the IV. It also works well in windows 10. The original instructions still apply although I recommend changing the installation path to C:\LTSpice or similar and moving path to reflect. (This avoids potential issues with write permission in the default installation folder.)

Note that XVII is not compatible with Win XP..
