OK, I got two ss20 power supplies... plugged in a power supply to the
20, put in the original sm71, powered up, and got... brief flash of
power light, and that's it. Possibly a disturbing smell.

OK. Now I need straight advice. I have 

1.) a newly remanufactured ss10 motherboard
2.) a supposed working ss20 motherboard
3.) 2 sm-61's, 1 sm-71 (probably an sm50 or two)
3.) one ss 4/5/20 power supplies
4.) one ss 10 power supply
5.) one completely working, in production, ss10 with dual 71's that
I'm not touching
6.) 1 essentially known bad ross dual 100, and
7.) 4 essentially presumed good ross dual 100's


If it were you... how would you go about it?
