Re: 419A Chopper Replacement

Many Ne bulbs have minute amounts of radioactive material in them to
stabilize the firing point. As the radioactive emission rate decays, the

That was my first impulse; however, the manual (paragraph 5-27) states
that "physical alignment and selection of the neon bulbs are critical"
and that replacement of the entire assy is the only thing to do.

Can you speak to this at all? If I _do_ replace the neons, are
standard NE-2 bulbs the right thing to use?

Thanks for your help!
