prs mt15

Just got the MT15 and it sounds amazing going to my 8ohm Randall rg212 cabinet. My question, is there any way I can connect another of these 8ohm cabinets? Or do I have to save and buy an entire other amp to have 2 8ohm cabinets running?

Hey everyone, I just bought a new PRS MT-15 yesterday... Wow! It has as much gain or more than my old EVH 5150 III 50 watt head. I have three types of preamp tubes that I am going to use to replace the 6 JJ's to try to tame the gain a little. In what position would you place these preamp...
