Input transformer?
Do you mean the AC power transformer? (The one in the middle.)
If so, I think its a bit unusual for a modern amp to have a noisy power transformer. I assume by noise you mean a mechanical humming or buzzing.
I would not take that as a good sign. It is also a condition that may get worse with age, though most likely the noise will stay the same. The noise is unlikely to improve with use.
"Hot" is also a term that needs definition. As long as the transformer cover is not so hot that you cannot place your hand on it I wouldn't worry too much.
