I was guessing R3 was meant to represent something like the internal=20
resistance of the battery/voltage source. This can actually be set in=20
the voltage source if you right click on it, along with parallel=20
capacitance.

Probably LTSpice doesn't have a TIP41, but I noticed TIP41 has been=20
added as text underneath, presumably to remind what this is meant to be.
There is likely a TIP41 model available somewhere on the net, which=20
could be used to create a new LTSpice component.
