It is weird looking at a radio of this vintage. Resistances may seem precise but they probably varied from radio to radio but not over 20%! The long resistance block was a 3 Watt minimum but for modern safety reasons you should bump that up to 5 Watts for each one. Since it ran off 110 Volts back then we now have 125 Volts or higher coming out of the wall. Any section not up to snuff and you might be dead in the water. I am not sure if you can check the tubes. One bad one will make it inoperable. Guess that is how they made things back then.
Agreed. My house voltage is about 122. I use a Variac when I play my radios. I keep the voltage between 100 and 110. I still need to take readings on the 5-part resistor. I’ll replace what I need to with 5 watts. My tube tester doesn’t take the older tubes. I checked the filaments. All the filaments are good so we’ll go from there. You never know, this radio may play again. Steve
Great video Steve. When I measure the resistance across the power plug on my working 511, I get 20 ohms with the Primary Tap Switch #29 positioned toward the rear of the radio and 18 ohms when positioned toward the front. I cannot find any reference to suggest what voltages the two positions represent and I haven't measured tube voltages yet. The resistor you suggested being a 10 Meg looks to me to be a 10K (Brown-Black-Orange). Where did you get the schematic you have that includes the component values? The only one I have been able to locate with values shown is the Canadian Philco 511 version and the values are subtly different than what I see on your copy. None of the US versions I can find have the component values shown except for the odd value in the parts list. Good job, keep them coming and thank you.
Look on Philcoradio.com. I believe that’s where I found the schematic. Under service info….early Philco schematics…511 series. Tons of useful information on that site as well. Hope that helps. Steve
@@My1925World Thanks Steve, that was it. The Philco site was the first place I visited but I gathered the schematic from the "Philco 1928-1936 Wiring Diagrams" section rather than the "Early Philco Schematics" as you suggested. Thanks again.
