Thanks to Ron and MFixr for your responses. Ron was right, that's what I was measuring. As for today I checked some voltages and here is what I got. It didn't seem to matter is I went to chassis or the filament. RF tube- plate 224, Screen 71 control 2, cathode 1.6. Det. tube- plate 232 screen 70 control grid 9 cathode 9.28. IF tube- plate 223, screen 68 control 2, cathode 1.7.
I also hooked up my signal generator to the control grid clip of the det-osc tube at 260 kHz and the dial at 55 and got the tone thru the speaker. I then hooked up the sig gen to the antenna connection at 1400 kHz and the dial at 1400 and got the tone.
Not sure what that tells me other than some of the voltages don't match the chart. Still working on it.
Thanks,
George
