Uhh, VERY Stoopit Question: WHY did they "Wash" the inside of the cabinet black ?

Well, uh, er, I dunno! You have hit on something I always took as normal, like living next to the tracks and never hearing the trains. I wonder if there is a good answer.

Edit: like maybe black is the cheapest stuff they could find to treat the wood against moisture or something?

I am going to count Steves California CT100 as a Wisconsin set because Steve is a Wisconsin native.

Hey Bob:

That's how I had it figured. We can't let Michigan win! If Pete doesn't see it this way I guess I will have to ship my California set back home!

Looking at Phil's photos you can see that they also included the vent holes at the top of the cabinet when they washed it black.

The CT-100 doesn't have the brightest screen in the world. It would likely be watched in a dim room. The metal back has a high optical transparency, better than 50%.

It has a gazillion tubes in it.

I think they painted all these surfaces black to reduce the amount of light that would shine on the wall behind the set from all the tube filaments.

I don't think they would have carefully included the top vent grooves/holes for any other reason.

Painting the interior black would make sense for heat reasons if it were a metal cabinet, but wood is a pretty good insulator. So the heat would have to be reflected out the back, in addition to convection cooling. A low emissivity surface would work just as well as a high one at reflecting the heat out the back so I don't think it was painted black for heat dissipation.

Actually I mean that a low emissivity surface would reflect the heat out and a high emissivity surface would re-emit it out.

In support of your theory John, the Merrill cabinet was not painted black below the chassis in the speaker chamber.

I just realized, a CT-100 basically has a "TV lamp" built in!
