Is the filter tracking working?
If so: sounds like the DCO dividers are not running.
Can you measure a rectangular waveform at pin 10,13,17 of IC 55?
Check all the Pins on the Juno-66 for continuity and shorts .
Especially Pins 10 – 23 and 35, 36, 38
You can also post a photo of the installed Juno-66, sometimes this helps..
