Hey guys,
I've changed my tubes out at the beginning of this year and haven't gotten around to doing many gigs with it. But for some reason it makes this sorta crackly sound on startup, then the whole thing buzzes like a fridge (and talks in maths <hint>)
Then after a couple of minutes it stops buzzing and does an occasional gas igniting sound, like a flag being waved sorta.
Do I just need new tubes?
