What's a "spot killer"?

Edgedamage:

Spot Killer Indicator
  A spot killer circuit is used to blank the CRT under a
  no signal condition. When the spot killer is active,
  the CRT will be extinguished and LED D504 will light
  indicating spot killer operation.

Ganked from wells gardner site.

I saw a astroids cocktail that had a little spot burned in the center of the monitor.  Is this what would happen to a monitor without a spot killer?

I had the chance to buy an Astroids Deluxe at an auction.  Wish I would have went a few bucks higher on it.  :-\

Yeah, but burnin isn't caused by a no signal condition... it's caused by a signal that doesn't change, right?

rchadd:

on ebay i've seen somebody demonstrate a tempest board was in working order by using a oscilloscope.

no really an option for a cab though

could use an old vectrix console if you can find one

any recommendations on which make of vector monitor is desirable? either color or mono

can you get them new?
