So, I just invested in my very first tube amp. I just bought a Mesa Boogie Express 5:25 short head direct from Mesa. Previously I had a Line6 Spider III 15w, so I made quite an upgrade. Deal is, I've gotta wait for about two weeks to buy a mesa cab, so a friend is going to let me borrow the Epiphone Valve Junior Extension Cab, which is 16 ohms. The express has one 8 ohm output and two 4 ohm outputs. What does this mean it can handle and can I even use my friends cab? I am a complete noob to all this ohm crap so don’t be afraid to talk to me like I have no idea what I’m talking about…

I don't know anything about this subject, but i think this article will give you the answer.

I think if you run it how it is it will work but with less power. If you could get another 16 ohm cab and run them both parallel it would have half the ohms making it equal.

I also found this that would solve your problem.

Thanks for responding so quickly! I actually just got off the phone with a mesa rep and he told me that because of the transformer that mesa uses in the express amps, I could go up in ohms and never hurt the amp at all. He did however tell me that if I create a situation in which I am running my amp into a 2 ohm cabinet situation, I will ruin the amp and be SOL. He also said that most other amps would probably work with that 16 ohm load, but they might have a transformer crap out. I love Mesa...
