Robin,
Looks very nice and clean inside. Now we all want to hear it 
. How is it heat wise as well? I noticed that my combo 2 stroke gets very warm. The Chassis is not quite too hot to touch but it gets hot (looked inside and everything seems fine). Seems like that would be an issue with an amp head where there is more metal to be touched and a more enclosed space. Do you need a fan or anything like that? Just curious.
