[Chassis Disassembly]
Updated 8/31/07

I decided to strip the chassis, and remove the rust. I thought that this chassis might be much better if I did it right the first time. Of course there is the risk that it never gets back together again quite the same way.. ;-)

That is why I decided to document my activity with photos so that there would be a record of everything I did to the chassis, and this would become a map on how to put it back together again.

It was interesting that I found a connection that was never soldered in doing this. I wonder if there was noise int he radio even at the beginning that noone was ever able to find? This was in one of the resistor cascades around the number 45 output tubes..

These photos document the chronology and placement of all the parts as I removed them from the chassis. I worked on this on the afternoon of July 17, 2006. It took about 4 hours to take the chassis apart. In order to try to make sure I don't make any mistakes, I used plastic bags for saving the parts. Everything, including the hookup wire was kept.

Once stripped, I plan on using Naval Jelly to remove most of the rust. I will need to use emery paper or steel wool to smooth out some of the remaining spots. The chassis will then be painted with primer, and a finish coat with a semi-gloss.

Once the chassis is de-rusted, and repainted, the parts will be replaced in reverse order. Each part will be tested prior to going back into the set. The tubes had already been tested and removed and packaged. Between the schematic and the photos, I hope I have everything covered!

The first six photos in the Chassis Disassembly section (three top chassis and three bottom chassis) provide a record of the original state of the chassis.. I have used a photo merge program to combine these into large detail photos which I can print on my large-format printer (11 x 17 inch format). I have included them at the top as Original Chassis. This will give me a good hard-copy image to consult if there is any question on placement of any parts. I also tried to get some initial close-ups in areas that may be difficult to view, or wiring that may be complicated.

This is the result of stitching the first photos of the top of the compete chassis..
You will notice some wierd artifacts (such as the electrolytic on the right).



This is the result of stitching the first photos of the bottom of the compete chassis..
