White Hiss noise on my hall and Collins echo

[mannes]

Today i want to play guitar
And a hard white hiss noise is coming out of my hall and Collins then patches seems to be heard far away I tried all of my pedals
And they were good
Yesterday there was nothing wrong
Does Anybody knows what the problem is??
Kind regards

Hi Mannes,
It could be a faulty transistor at the main output. Please contact [e-mail] for advice on how to have it repaired.
