one last check, did you check the voltage on the CRT pins? just wondering if the tube could be cut off. Also do you have a HV meter (dont recall if this has already been covered).

I let the CRT run for several hours Saturday and Sunday this past weekend. No changes, other than the vertical height changing for the better after a few hours playing. Hooked up the OEM tube, and while very dark, the picture was sharp and clear. Ran Gone With The Wind on it on Sunday. The burning of Atlanta never looked so dark! I'm not doing anymore until I get another tube in my hands.

did you try different settings on the magic eye term strip? I think if you just unplug you get the brightest setting. When its is enabled then a dark room just makes it darker, try the flash light on it to see if it gets brighter.

It makes a slight difference when plugged in. It's unplugged.
Even the OEM tube looked brighter before I applied 7 volts to it. It's intermittant now. brightens up and goes dim, brightens, dims... I'll wait to do more when I get the replacement kine in hand. I look forward to this set playing. Last edited by holmesuser01; 05-17-2010 at 06:20 PM. |

The HV is about 14KV. I have a meter. Checked CRT when I started out. There were no abnormal readings.
The set was run into the ground by the original owner, according to his son. For several years, the old man watched TV with the curtains closed in the living room until the kids bought him a new set back around 1989. Then it sat there waiting for me to come across the street and grab it! I've got it moved out of the way for now. Just a-waitin' for the kine to come along... |

AFAIK, The Emerson is still there. The ad is still up, too.
I bought the tube from Larry in Texas. I went to the Greyhound terminal yesterday and picked it up. He did an outstanding job packing it. I bet it could have survived a good toss... but I'm glad it didnt. If I get lucky, I will get time this evening to do some work on the Maggie. |

It's been several weeks, but this morning, I got the 23MP4 installed in my set. It was an easy swap. The tube installs from the front of the set. I bet it only took 10 minutes from the time I loosened the strap on the old CRT, to when I snugged up the strap on the replacement. Didnt even have to pull the chassis. I just vacuumed out the cabinet thru that big hole where the CRT goes.
It is now running, and looking good with no adjustments so far. The width is low, but that could be due to caps. I've only replaced 6 so far with good results. The turntable was replaced at the same time with one out of a stereo I found down the street from my house about a week ago... Finding 2 Maggies within a week was wonderful. I watched a couple of old Bullwinkle shows on a VHS tape to 'break' it in. The picture is improving the more that it runs. The video sentry on the front of the set is now working. I want to thank everyone for the moral support. This set will be running perfectly shortly. I will post pictures, as I took some while I worked. I'll have them up later. |

See Pics. I even glued the OEM label for my old tube onto this replacement.
Enjoy. |

More Pics. The bars in the pics dont do the picture justice. It looks great now.

Dave, I spoke to the lady with the 22" Emerson. She gave it to someone I know. I think that he might call on me for help. He has more space for TV's than I do anyway.

GREAT!!
Glad to see it up and running. I found my CRT gets better as I use it (seems that way anyhow). How does the fly look on that one, the ones on my maggies are pretty nasty but still work fine. |

The fly has been hot at some point, but is running fine, so far.
It rained tonight. I turned the set on for a little while, and the dampness has some HV discharge radiating away from the HV connection. I'll look into that further in the morning. Tonight, no gassy tubes, and no red plates. Played an Addams Family show and listened to the sound. Still need to gain width. |

Just curious, I assume the width control is maxed out? thats the coil down below the HV cage. Can't recal if it goes in or out for max width.
