Did a little adjusting today. Tomorrow I'll start the alignment.

Been busy with other things.
Here's a picture of all the caps and resistors that I changed out. |

Update!
The chassis is finished. It's been aligned and detailed. The final set up will have to be done once it is installed in the cabinet. I've cleaned the cabinet inside and out. I also polished the outside. I filled in the lettering on the front knobs and the logo with gold paint. I'll spray on a new coat of gold that surrounds the CRT tomorrow. I got the paint from the craft section at the local Walmart. |

That is looking very sharp. Personally I'm not a huge fan of painting chassis and parts. I guess I just like seeing some patina on old things. I can live without the dirt, but all the little blemishes just add to the nostalgia experience for me. But I have to admit you have an awesome skill set and you make these look about as perfect as anyone could possibly ask for. The gold paint really makes that lettering pop. Overall you've done a knockout restoration.

Excellent work. I can't wait to see it completely assembled.

A couple of questions!
What was that small selenium rectifier used for? The octal tube base next to the 19BG6 has what in it. I saw one 60 years ago and that set had one that had a neat little perforated metal cover on it. It seemed to be a surge limiting resistor in it, but a tiny one. |

That socket is for a Ballast resistor. On this chassis, it was just a piece of wire. Both can be seen on the schematic below. BTW, Emerson had drawn the symbols for the diodes backwards. My pencil marks are the correct way. |

Regarding the diodes there was a lot of controversy back then over which way they should be drawn. Possibly because of conventional vs electron current flow.

They at least bothered to draw the + marks right so that the production floor installed the + marked end of the seleniums correctly...

One of the final pieces of the puzzle was the small plastic piece that fit around the edge of the mask that faces the CRT. This is to give a nice appearance rather than just an edge of sheet metal. This piece is "J" shaped with the smaller side visible from the front of the TV. I tried several times to find a suitable piece of plastic to no avail.
I then thought of a small piece of silicone fuel tubing that is used on R/C airplanes. This tubing is translucent in color and very flexible. Hmmm...... The stuff I used was 2mm I.D. and 4mm O.D. I had to split is down one side. I made a jig so that I just inserted the tubing into the jig and I then just pulled it through. Perfect! I then slipped in onto the mask, cut it to length, and then used some medium super glue to hold it in place. This worked out very well. |

With that finished I was able to put the chassis back into the cabinet. Cut some felt for the knobs, inserted the speaker, vent, and hold down straps. Finished, except for the back. BTW, does anybody have a picture of 614D, or maybe a 650 back that they could post?
