Of all the Philco radios I have worked on over the years...and I've worked on hundreds...I have observed that Philco started filling the eyelets with solder sometime in 1936. These appeared in 1937 model Philcos and continued until they discontinued the bakelite block altogether shortly after World War II.

At the same time...1937 models Philcos were the last to use lots of bakelite blocks. 1938 models began to make more use of the conventional tubular paper capacitors; by the 1939 season, generally only one bakelite block is found: the AC line bypass.
