Model 60 volume and no frequency
#14

Steve, you are correct. I combined the 70,000 resistor with the .5 meg (470,000) resistor on the 8035-D condenser. I corrected it to put it on the same condenser as original and per the schematic. I have a Philco 42 but using the RCA-42 and this time I allowed it to properly warm up. I am re-checked voltage using my volt meter (yes, Madmurdok I do have a cheap volt meter exactly as you stated). this time the 42 is reading H & H both 0, k G3 = 0, G1=3.5, G2=272, P=265. To Madmurdok, you'll notice the book is purchased off ebay and I will read it. I want to understand this - I'd like to make a hobby of this. 40's and 50's radios were a lot easier than the Model 60 but this is REAL radio to me and will open up a whole new world if I can get my feet on the ground (with one hand in my pocket). Steve, I check voltages before I connect anything now - thank you.
real mystery to me is I can't inject a signal even at 42. I can connect to a modern AM radio and find the 400hz tone like crazy. my speaker is silent beyond a low level hum and when I touch something I shouldn't and it screeches. after putting the .022 in series (validating with modern am radio) I get nothing at 42 or 75. From your description is this the most basic audio test. Meanwhile I'm examining the schematic and see if a resistor is wrong. I've been working on the cabinet so this will be my show piece if it can get working again. thanks for all your help! Rich
