I have a 60watt machine but the tube is fried. Since I'm getting a new one anyway, I'm thinking of getting an 80 watt tube for now, then upgrade the PSU later . Is it possible to use a 80 watt tube in the 60watt setup, and still get the full 60 watts from it? I know I wouldn't get the full power with a 60watt PSU, and it's significantly longer, (I'd have to let one end stick out,build a cover for it) What, if any, problems would that cause? Has anyone tried this? I'm inclined to believe that the 80 watt would probably last longer at higher power than a standard 60 watt at high power. Am I way off on this thinking? Thanks in advance for any assistance anyone may be able to give.
