Hello Doug
Regarding 2SC1971 transistors: I believe an MRF237 is also equivalent, although not a TO220 package.
A 'real' 2SC1971 is a very rare commodity, apparently, because they haven't been made by the original manufacturer for decades.
I believe Eleflow is a reputable supplier if you want a suitable replacement. http://www.eleflow.com/
