Zenith G730 AFC questions etc.

The silicon diode that replaced the selenium rectifier has to be there, but it can hide, it's so little. Probably under the chassis. In the post that I referenced I circled where I put mine, but the last repairman on yours could have put it anywhere underneath the chassis. Here's a picture of one with its schematic symbol. The end with the line is the cathode and that end goes towards the B+ plate voltage of the radio.
