Manufacturers don't get it. make tubes visible.

I love the glow of my tubes and the look of two mono blocks with there tubes proudly displayed, not mention the real reason... the sound.
I do agree some of the amps are ugly.

No lava lamp for me !

I dont want or need to see tubes to know they are there, I dont care for the exposed tube look and would but a closed unit if I had a choice.

Actually tubes are a very useful tool for creative arts. I forget the name of the guy who finds mercury tubes and builds amps with tubes placed in what appear to be a random pattern around an antique meat grinder.
Joe why not just angle the tubes so that they form a an oval peak. Start low and reach an acme. It would be very cool if you could have them project further as they climb. No I think it would be grotesque. How about a diagonal strip of tubes on a mirror polished chrome /Steel top. or an X patter put a optical blue light under a simple strip of plexglass as the tube cage with just the tube tops poking thru holes in the plexiglass.Well I willkeep thinking,eventually should I livbe a long life about one thousand years statistically I'll come across something. Good Luck honestly just watch out for sticking right in the front angled upward they would look like a miniature male process ready for action.

Furthermore...the chassis ought to be glass, so you can see and gloat over all those expensive capacitors and resistors. Hopefully they don't glow.
