Hello, 
I just joined the Philco Phorum.  as an avid antique radio enthusiast ,I have always been impressed with the quality of Philco information. Some years ago, I found a Philco 511-tabletop (circa 1928.). In addition , I have several other Philco radios as well, and ,again, have been impressed with the tech data available. But, unfortunately, it must not have been available in the late 20's---or at least I have not found it! I am retired now and have more time to work on radios.
I have spent time doing some basic cleaning,tube testing, and trouble shooting. The 511 just stares back--All the tubes checked good and the filaments are glowing. Also I seem to have all the basic voltages from the transformer,as shown on the Rider sheet. The radio remains silent.  I do note that B+ is missing-hence the silence-I have checked the voltage divider--resistances seem in tolerance---BUT missing the 70K ohm  resistor. I question the condenser pack also. On this unit, none of the transformer or condenser terminals are numbered.
Is there more complete data available?
Also--what is the LOC terminal and how is it interconnected ? An antenna and ground were connected.
Any suggestions ? 
Thank you!
