3. turn the 3 position knob to dc, then measure the 125v source, see that it reads 125.
4. check tp5 again, see if it saturates at what the 125v source is...

I followed each step and got the attached pics. The DC of the 125V source (B2) reads just under 140VDC (with my DMM I get 130VDC). When I then check the DC of T5, I get 175V. This is with the same v/div as the previous test (50V/Div).
