Joule Thief behavior question.

Paralleling transistors is like paralleling resistors. The more you put in parallel, the lower the e effective resistance will be. However, paralleling transistors can be tricky. I recommend only paralleling identical transistors.

So, there is no way to know what numbers are changing so you can go out and look for a transistor that has the same specs as the multiple ones in parallel end up having?

When using identical transistors, every time you double the number of paralleled transistors the effective "on resistance" is cut in half. However, paralleling transistors is usually done to allow switching a current that exceeds the maximum collector current spec.

Which value is that on a typical transistor datasheet?

Something isn't making sense.  You show the collector current of 1.5 amps so if I put two of those in parallel you said that would be cut in half so that would make it 750ma which i not good.
