[Heathkit] Tubes

[rbethman]

Even doing LEDs won't have the same look and effect as lighting filaments.

The LEDs would have to be placed INSIDE the tubes.

Then you get the issue of the "getter" causing the "frost" that gets 
created when the envelope is broken.

These type of "Old Tech Candle" displays bring on their OWN hazards!

They have to be kept from curious hands!  That is precisely WHY I 
haven't done this.  Even though I've got a bit of a collection.

Let's see, 813s, 65TH, 3-400, 4-1000, 807s, 1625s and numerous others.

Keeping them in a closed cabinet brings up issues of cooling.
