Looking at the circuit diagram annotations I think you may have driven it
slightly into over-current protection with your dummy load, and that could
explain your voltage drop.

-12V should be 0.3A == 40R (you don't say what you used for this)
+5V Should be .37A == 13R5 (say 15R) so your 11R is too low
+12 should be .45A == 27R so your 22R is too low
+55 should be .3A == 183R (say 200R or 220R) so your 230R should be OK
+110 should be .023A == 4K7

Well, -12V and 110V was left open, no load there.
If you add the loads together I dont think I'm overloading it.
Also dont forget when connected to the scope it overloads too.
The rest of the scope works fine.
