John Larkin doesn't like designing his own transformers and inductors and g oing to the trouble of finding people to wind them for him.

Krw may be an exception there. Jim Thompson posts a lot of links to right-w ing political rubbish, which is to say he farms out his thinking to a sub-c ontractor, while John Larkin's opinions about climate change seem to come m ore or less directly from Anthony Watts denialist web-site, which is buying in a disreputable product from a dubious supplier.
