I see lots of tube amps with the tubes mounted such that they point down. This means all the heat rises up into the chassis. This seems counter-intuitive to me. All those components baking all the time. Is it just for convenience? Eric

He has a newer machine with a VFD on it and asked me how he could get the same thing on his old machines. I told him he really needs to change motors to 3 phase. But he is loathe to do that. I can see w...
