Yep, I've used a 220V muffin wired to 120 on my T4X-C for 30 years. Just pull the cover off the case every year and use "canned air" to blow the dust out and off of components. Dust WILL collect under the chassis too... (Yank the power supply connector before doing this!)

In my past, I used Drake twins on RTTY and ran two 115v fans in series, one over the final compartment and one over the PTO area to draw out the heat. They turn slowly, but fast enough to aid the natural convection, and I never had any trouble with excess heat. Of course, I was running the T4XB at about 50w out, not full bore, hi. If you can find them, 230v fans on 115v will start and run slowly for quietness too.
