Will do. I don't have a variable-limit supply, but I do have one with a
fixed 1.5A limit that I plan to use for initial low power transmit
testing.

That will help you not fry some of the bigger stuff but there is nothing
like a 0 to 15 volt, 0 to 35 amp supply with volt/ammeter.

Even better if it has OCP. If the current drain reaches a user programmed
setting (IE those BJTs are about to blow!), the power supply will shutdown
its output completely, instead of just dumping continuous current to
whatever the current is set to.
I have an Agilent 6643A which does this. While they cost $3K new
you can pick 'em up for a 10% of that on Ebay. I paid just a bit over $300
for mine.
