Colorful amps

It doesn't have to be all grey or black, you know?

Oh mine gott... Hot tubes squeezed between metal boxes almost touching electrolytic caps...

How long do you think this Lego will play before making loud Bang and throw confetti on a ceiling?

You have engineer's eyes. I'm only an artist.

How long do think this will run before that pretty Orange and Yellow paint-job will discolor from heat build-up??
Or..how about those power resistors at 0:40 and 1:55....clumped together...very little convection cooling going on there.........I do hope the designer has these resistors running well below their ratings. If not, this thing will overheat. "Whats' that smell honey?"
Poor heat management.

The tubes are crammed in there pretty tightly.. I think most of the caps are motor runs rather than electrolytics, (At least for the part I watched) but this really is no excuse for placing them so close together..

The amps are "pretty," and have a lot of very expensive parts in them..

I have an insight: it was designed in a boutique that used to design nice and expensive ladies' hats!

Seems highly likely to me too, and we ain't talkin' about our resident blond either...

From the design school of "form before function."

We're a catty bunch aren't we?

Hey, I resemble that remark!

I have already built a few amps that border on poor thermal management. The industrial amp Simple SE is an excellent example. Everything is stuffed on a chassis that measures 10 X 12 inches on the top but is 8 X 10 underneath. I have found that it sounds best with EH KT88's biased at 80 to 100 mA each. Yeah thats about 200 to 225 mA out of a power transformer rated for 150 mA. Can you say toasty. It has been running for about 4 years now, still has all of its original parts. After about 4 hours you can't touch anything. Even the volume knob gets hot! I figured I would rebuild it (bigger) when it blew up.

My Tube Cube may prove too hot for long life, but there is only one way to find out. It cranks out 100 to 120 watts from a 12 inch cube.

There is an easy fix for heat fried paint. Use automotive engine paint. It's good to about 450 F and comes in several glossy colors. For the really hot stuff use header (exhaust) paint. Good to 1200 F but only comes in flat colors.

My wife is also blonde, but her blondness comes in a bottle. I keep reminding her that excessive amounts of that blonde sauce soaks into her head and makes her stupid!
