The plates on the 6BQ6 are black. What's going on here?

The plate in the tube can glow red if the Oscillator isn't running.

The squealing noise would seem to indicate that it is though, if it's loud then it's probably not at the right frequency.

If you pull the connector off the top of the 6BQ6 tube does the noise stop?
