Hi everyone. I hope you all had a fun holiday season.
I've been (s-l-o-w-l-y) working on my 19. I have the innards of about half of the bakelite blocks replaced. A couple of days ago I decided to tackle the tone control. I've uploaded another picture to flickr and I will try to describe the problem. Here is the picture:
http://www.flickr.com/photos/104710683@N04/11894578244/
I added a text overlay identifying the tone control near the upper left. Just to the right of the tone control in the image is the on/off/bandswitch. I need to remove the tone control assembly (Item 53) in order to replace the two caps that are contained within the 'box' of the tone control. The problem is that there is a lot of stuff in the way and I can't push the assembly back into the radio far enough to get the shaft through the hole.
In the image, just under the paper label on the tone control box, there is a piece of the chassis that was bent down to serve as the mounting point for the two electrolytics. I have removed C44, the electrolytic that is closest to the tone control, but there is still a semi-circular collar that is used to hold C44 to the chassis bend-down. I unscrewed one side of the collar, but it looks like, even if I removed the collar, that there wouldn't be room to remove the tone control as the wafer/switch portion of the assembly (underneath and mostly out of view in the image) hits either the chassis bend-down, or the on/off/bandswitch assembly, or both.
Has anyone else had problems removing the tone control from a 19B (code 126)? How were you able to get this out? I thought about trying to replace the caps without removing the assembly, but I don't see how I could do that either.
Also, a related question: Assuming I am ultimately able to remove the tone control assembly, how do I get the existing caps out of the box? On a bakelite block, you heat it up and stick something through one of the top-side holes to push the contents out. This box doesn't seem to have any holes. So what is the trick there?
Thanks!
Jon
