The whistling noise is coming from the speakers, not within the casing of the amp, so it's getting mixed in with the audio signal at some point. I had a look inside for any obviously bulging or leaking caps, and couldn't see anything out of the ordinary. Judging by the fact that the display has an impact on the whistling tone, is it perhaps worth reflowing the display pins, or checking any caps near the display?
