Hello Philco Forum members. I have run into question while reassmbling my 37-640. I have attached a photo of the rear of the chassis with the red arrow pointing to the screw and the flat metal slide sbove it coming out of the chassis top. Can someone tell me what this is and should the flat metal slide do something other than confuse me? Should the slide move up and down?
When I get this all put back together, I will explain all that I had to do to replace the broken bandswitch wafers in th rear of the RF unit and replace all the wires coming from the bandswitch. I still have to try to repair a broken wire in the IF transformer when I remember which transformer it is. I have never done that type of repair before so I will try to read up on it.
Thanks, John
