So I'm about to get my second Traynor amp Saturday. I have the YCW20WR now, and love it. To get some more headroom, I'm picking up a YCV40WR Saturday. Through swapping tubes out of my 20, I've noticed the metal enclosure around the tubes. Through playing, I've noticed how ridiculously hot the amp gets due to this. Has anyone had one of these Traynors/another amp, and had an issue with tube life/hardware malfunctioning over time due to the insane heat produced and contained by the enclosure in these guys?
