It's alive! 
Today I completed recapping the set. Upon intial powerup, though, I heard a sizzling noise coming from the input filter cap!
A thorough check of the circuitry found nothing amiss. So I replaced the new 33 uF cap with another new 33 uF cap.
That took care of it - the set then came to life without any further issues.
Every once in a while, we find a new cap that is bad; and that was the problem here. Fortunately, it does not happen very often. I think I can count on one hand the times it has happened to me over the past 36 years of restoring radios. And a LOT of radios have crossed my various workbenches over the years.
Here is the CR-188A chassis, AMP-101 amplifier, and the two 12 inch speakers spread out on my workbench. As you can see, these items took up nearly my entire bench:

After an alignment, the set is back in its cabinet and playing as I type this. I can hear it playing downstairs (my computer is upstairs). I'm a happy camper.
