Your first problem is you are feeding DC to a transformer.
The bridge rectifier need to be AFTER the transformer.

Dear Greenkeys community,

I'm trying to build my own power supply for my Teletype model 19, it needs 120-130VDC of power @ 830Ma. I'm working on a circuit for it, but I don't exactly know what I am doing because I've never done this before. Would you let me know if I am on the right track to building a switching power supply? 
P.S. I know it needs a snubber circuit somewhere and none of the actual switching circuitry is there, I don't know enough to know what goes where.
