An open input won't cause a loud hum with a working amp although there may be slight hum. The hum will be affected by the volume control and the OP had hum even when the volume control was at zero. The nulling of the hum at a certain volume setting indicated something very strange was going on, since it meant that two out of phase signals were being mixed at some point, one of which could be adjusted by the volume control to get the null.
As the subsequent posts indicated, something was seriously wrong. Fortunately, the downside of this electrical fault was only an annoying shock and blown components. It could have been much worse.
