Just lucked into a Traynor YBA-1A Mk II. Consensus seems to be that it puts out somewhere between 45 and 90 tube watts at 8 ohms. So, if I plug it into my Ampeg SVT 410-HLF (4 ohms, I think can handle 400 watts), am I going to overheat and destroy my cab? Or will I be ok? Just wanted to get some opinions before I give it a try.
