ST70 power transformers are known for their mechanical hum, specially the older ones. One of the selling points of Triode Electronics ST70 replacement power transformers is that they "won't buzz & hum like some originals do" If the hum is getting to the speakers then you probably have a capacitor or a ground problem.
