norm,
Are you certain the Elgar unit is working correctly? I see that it's advertised as having sine output. I'd try a simple step-down as a sanity-check, à la https://amzn.com/B000WMK6QY.
According to the literature the transformer in the 101 is a potted toroid. If that's vibrating, something is VERY wrong.
