@captain pugwash The original did have current limiting but many people omitted that circuitry entirely.

Sending quick recognition for (1) the super high quality PS PCB and (2) the BOM in the rev1 pdf on page 1. On the former, the paths and vias are generous. As is the font for those of us with not so young eyes. On the latter, the recommended Epcos 400uf capacitors truly 'snap in' and look to be of excellent quality, especially considering the reasonable price. You can see I've elected for the 4.7ohm thermistors anticipating 1.4A bias.
PSU tested and functioning! Reading approximately 26VDC on both + and - with line voltage 121.6VAC.
Thanks again to @poseidonsvoice for taking time to provide a detailed explanation to my question. I leaned something!
