1. What kind of meter do you use? A todays DMM?
2. Do you have the original speaker and does the Field coil have the proper resistance?
3. What is our Rectifier cap's value (should be 8uF), I think it is #68.
4. Are your resistors #30 (21 and 263 Ohms) OK?

Oh! There's that mistake in the sch again.

How did you connect the Cap #67 that goes to the Resistor #54? It needs to connect to the B+ after the field coil. And the dot is missing.
