It seems to me that the only "stress" that would be placed on any of the amps, if they were "stood on end, upright", would be on the tubes themselves. Of course, the faceplate/top plate would need to be secured, but presuming they were secured, would there be any short or long term detriment to standing any of the amps on their end, so as to make more room in their physical location? The tubes, in the limited amount of experience I have so far with BH gear, seem pretty snug. is there any long term reason not to stand any of the amps up?
Thanks
