Jerry;
Thanks for the comments! Here are a couple of pictures of my solution for this particular chassis. I realized that it would be impossible to do any sort of decent alignment with it in any other position than standing on edge. I do not have the adapter sockets that Philco describes in their alignment procedure, so I will be finding a way to couple signal in from the bottom side of the chassis. This platform was made this afternoon using some left over 3/4 inch plywood, some large right angle steel brackets and some wood screws. I used the chassis bolts to hold the chassis to one steel bracket on the front side and to the vertical piece of 1 X 4 on the back side. It is nice and stable enough to make the rest of the job far easier. One thing that would make the job even easier would be to have a 4 or 5 inch field core speaker with the right field coil resistance. The 12 inch unit is cumbersome on the bench.
