The problem is I have an unknown condition CDS3 and I need a mockup PSU to check if the player is worth the trouble. I think I can build something akin to Teddy but would need a simple solution first to check viability of the whole enterprise. getting a "door stop" regulator board with matched proven quality of simple 317/337 regulators is the easiest path. The alternative are Chinese boards with who knows what parts. A person whose opinion i kind of trust indicated that old stale PSU sounds better with CDS3 than DR version. XPS-XPS2 board would work too.
