I don't know if anyone else gets this issue with any amp, I have a fender bassbreaker 15 connected to a Marshall 1936 2x12. After about 15 seconds of turning the amp on there is for about 5 seconds an increasing in volume popping hiss. Then it stops and the amp works fine. Is this something I should be worried about?

Re: Either amp or speaker causing initial hiss
Do you use the mute switch, when you firing on your bassbreaker? If not, you should. These are tubes which need some seconds to warm up and work properly. The mute switch shuts off the high voltage and you can avoid stress on the tubes while they are warming up. Helps to extends tube life, too.

I can’t directly speak to that particular amp since I’ve never owned/played one but I can tell you that my Marshall 2204 makes those type of noises when the power tubes are nearing the end. Kind of it’s own early warning system.

Probably not tubes breaking in, but it could easily be the tubes warming up or possibly the filter cabs charging fully.

Re: Either amp or speaker causing initial hiss
The hiss can't be from the speaker, speakers are passive, something active (amplifier) has to be connected to them before they can do anything.
Not sure what is going on, it may be nothing, but you also stated that the amp was brand new, I might take it back to where I bought it and compare it to other ones there to see if they all behave the same way.
