I know that this has been discussed many times and I know that it is common knowledge that these little amps are known to get hot....but my goodness it scares me how hot mine gets. I only use it on occasions with my 4ohm SWR Goliath Jr because I love the amp and I want it to last forever. We played a three hour gig last night and I was once again shocked at how hot the amp was so I started shutting it off between sets. I do not know if that will help preserve the life of the amp. I think I am going to add a little fan when I gig with this amp.
