A friend of a friend asked me about some mixer-amp, make unknown.
It works fine but every now and they see a blue flash through vent holes.
Presumably before the reservoir caps and a break at mains volts, but what?
A green flash from a seriously overloaded fuse rupturing, but that would be
one-off, but what could give a blue flash ?
