Hi and welcome to the forums.

You say that it's getting extremely hot, but it very much depends on how an individual person difines the heat as being extreme.

If it's hot to the touch, but you are able to bear your hand on it for a sustained period and there are no obvious or abnormal burning smells evident then I wouldn't worry too much.

Alba weren't a particularly expensive brand, so the components used were likely to be adequate to the requirements but some were on the breadline (mainly the mains transformers).

So your unit will get quite hot on long runs, having said that, I wouldn't expect it to be really hot within the first twenty minuites of use. Just keep an eye on it, as although it may be working well the capacitors in the amplifier are getting on a bit now, and may be a bit leaky, which inturn will draw more current.
