Restoring Philco model 87

Don't do that, there isn't enough room under the chassis. Plus, such a job will be very sloppy.

The filter condenser can has a set of terminals built-in, on the bottom. The bottom piece of metal, which contains the terminals, can be easily removed from the rest of the can - you do have to remove the can from the radio first.

If you remove the can, take lots of pictures and notes so you know how everything hooks up before you remove it!

Now, with the can removed, remove the bottom piece as I mentioned; it easily pries off revealing several wires connected internally. Cut these wires and set the bottom piece aside.

You must now remove the innards of that can, which is sealed in tar. A small torch will melt that stuff out, but it is very messy and is a job that must be done outdoors.

With an empty can, once it cools off, you may want to give it a fresh coat of black paint as the heat from the torch will ruin any remaining old paint on it.

Go to my website, and look at the 87 diagram:

At the top right of this image is a diagram showing how the capacitors hook up on that terminal board that is the bottom of the filter block can. Notice In included positive signs in case you use electrolytics, but many guys prefer using metalized film capacitors here - they are larger physically, but should last longer.

Imagine this diagram in mirror image, as this is how you will have to connect the capacitors - they should go on the side of the terminal board that will be inside the can when you are finished.

This involves some work, but will result in a much neater installation.
