Re: Mullard 5-10 amplifier
Theres definitely a problem with hiss, 80mV of hiss is annoyingly loud.
I don't know where to start looking, it's obviously somewhere before the output stage but I'm finding it hard to see on a scope.
The photo is what I'm getting at the speaker. It sometimes gets worse but goes back to this level with a tap of a screwdriver.
