I have the 15 watt 65 PRRI with the 12" Cannabis Rex in lacquered tweed, and it's now my do everything amp. It sounds great in the bedroom, and the C/Rex speaker is efficient enough that it has PLENTY of volume in a band environment! I just put it on top of the flight case if I need to hear it with a loud band. Plus, it weighs only 34 pounds! Just grab & go! PS. I think all the PRRI's have tube rectifiers.
