What happens If I use too weak output transformer?

[jule]

I built 5W SE tube amp (ax84 P1)

I recycled an old tube radio - I used tubes(el84, rectifier), and both transformers.

But on the radio it said it had 4W.

The amp works fine, when I cranck it it squeals (but probably because bad wiring).

But I am worried what can happen with too weak OT? It could be that OT is more than 4W, but how could I detect the behaviour of weak OT?

Dont' worry! First: I doubt if you are really getting 5W out of a class A SE EL84. Second: say you get the, it will only do this in the peaks of music reproduction, so unless you listen to full sine waves at max power you are safe.

Then I'm ok (it is a guitar amp).
