Ok,
So I want to rack up 8 channel strip preamps that draw 25ma from
the plus and minus rails. 200ma per rail total for 8 strips. This does not seem to be such a hefty power supply requirement. I need +/- 22vdc.
(each strip has local 16v regulators). This supply seems to be enough
but I am suspicious that I'm wrong.

The 1970s mixer the strips they came from was powered by a MONSTER rack mount supply with big mofo trannys and HUGE can filter caps. Heat sinks run down each side of the outside of the power supply with 2 regulators per side. Weighs about 50lbs and is the size of an old power amp.
The mixer was a 22 channel and there were meters and things to power
besides. I just don't want to under spec my supply as this is the first
supply I would make for a multi module rack job.
Thanks in advance.
