Headphone Socket Use Marshall Head 100h Code


 I have just received my first ever Head Amp. So very excited about it. My question, is it totally unadvisable, to test out the headphone socket without connecting up a cabinet to the head amp? 

I was hoping to test before  obtaining a cabinet  (212 I had in mind).

However it does not advise using it without a cabinet connected. Is there a risk in blowing up the circuitry otherwise? 

Thanks for taking the time reading this.

Hi Rick,

Thank you for your comments, we always recommend the amp is connected to a cabinet while in use. This is to protect the amplifier while being used.

Hi Rick,

please don't use it without a load attached. You may be lucky and get away with it for a very, very short time, but I suspect as it's your first head it'll possibly be f**ked for good and if you have similar luck to me it'll likely burn your home to the ground too. 
The emulated out / headphone sockets aren't the best way to hear your new amp as it deserves to be heard and may even disappoint.

I'd urge you to loan (if at all possible, maybe even hire) any suitably rated cab and crank the thing up nice and loud and appreciate what you have worked hard to purchase. I'd even advise against any kind of dummy loads. They can fault the same as anything else. Headphones (even quality ones) are at best okay for late at night, but unlikely to provide anything like the tone you want to hear. 

I expect this piece of kit has cost you more than just the cash itself and is something you have desired for a while? Please (this sounds awful and also makes me sound a proper c**t) but you may need to be patient a little while longer. Every minute will likely be killing you and I feel for you deeply. I promise though, you definitely won't get help from anyone should things go "tits up".
I'm positive you'll enjoy the fruits of your labour soon. 
Take care,
Best wishes,
