Don't know what to tell you bout testing the emitters. I would test the way the sams says to. We are trying to figure out why the setup does not work. Until you get that working I would hesitate to work on anything else.

I think the bias voltage are off, so i would concentrate on those transistor voltages.

Okay, I'll flip her over and open her up to test the emitters directly from the socket and not through the attach resistor. Also, if I were to pull the transistor, wouldn't this also allow me to test the resistor? It would be the same as cutting one let as without the transistor in the socket, there's nothing connected to the leg.

I think there's an issue with the scope. If I put the probe in the vertical input, I get a nice tall waveform. Only issue is, I need the horizontal input for what we're checking. Also, I noticed that when measuring the horizontal, the waveform distorts when I put my hand near the vertical input or sync amplitude knob. This poor scope has seen better days, I guess. I think it's over 50 years old.
