That looks aboutright, the 269EX was designed with a 115VAC primary, so with today's AC line voltages running about 120-123VAC, the secondary voltages will run a tad high, not to worry...
The 47 uF cap might have been overheated, but unless it was really "barbecued" it should not have gone bad from soldering.
Check the PC board to chassis grounding, and depending on the OPTs, there is a slight chance that they might be picking up the stray magnetic field from the power tranny, a simple test for this isto take out the 1626s and listen for a low 60Hz hum is present. The GXSE15s have end bells andalso should be adequately magnetically shielded.
I ran into this, several years ago, while pre-testing a design with a Hammond 261M series open-frame power trannie and two 125ESEs. The PT's magnetic field, in this case, radiated out to about 18 inches. The 269EX has end bells, and is properly (magnetically) shielded, so this should not be the case, under 99% of normal conditions.
