Hi Phil,
Looking at the pic posted re bakelite block #75 in Post35, look carefully at the middle taqb and ensure that in fact, there is no wire soldered to it. The connections made to the 3rd "blank terminal (no connection internal to the block) is a standoff meant just for the purpose of acting as a terminal for eternal connections instead of the connection just hanging in the air. Comparing most Philcos to most non-Philcos, the non-Philcos use multi-terminal strips for interconnections with most resistors or capacitors hanging between these terminal strips and a tube socket or from one strip to another. Philco made extensive use of these blocks, probably as a shortcut to ease of assembly. Remember, this is the depression, and in the 1920s, you could buy a Model T cheaper than some radios. Radio prices had to drop precipitously for manufacturers to sell radios. RCA Radiolas went from $150 for the Radiola 60 to $72 for the R-7a "Suprette", a much better radio with twin Push Pull pentodes and 5 Watt output, variable mU tetrodes and an 8" electrodynamic speaker built into the set as opposed to the Radiola 60 with all triodes, 0.7W output and speaker at additional cost (about $35 for the 103 magnetic speaker or more than $100 for the 106 electrodynamic in a large cabinet. the Philco Model 20, a seminal radio sold for $49.95 (without tubes. 2 years later, the 80 Jr, a 4 tube superhet sold for $18.05 with tubes. Some of this was due to better mass production techniques, some reduction was due just to belt tightening and gettiing what the market would bear which was a lot more in the 1920s than the 1930s.
