Hi, Im sure this question has been asked before but I can't find it on the board. I have an all tube head (1975 fender super twin) and I need to grab a cab for it... My curiosity is whether a 400 watt or more cab would be fine. I know tube and solid state wattages are the same but I can't help but feel that this thing puts out a ton of power... It's louder than any 400 watt solid state head I've ever heard and id hate to blow speakers out of ignorance... What's a typical set up for a 200 watt tube head? Thanks!
