Step 1 alignment went well. Peaked up the 10.7 MHz if and the tracking of the front end. That brought a nice improvement in sensitivity and put stations where they belong on the dial. Also it improved the auto switching to stereo mode. A small portable receiver at the same location shows the signals are not very good in the test location, so I will try running in a better spot.
Next, I am starting to think over the "IBAM" grid bias adjustment and resistor/ cap changes needed on the output stage.
Fun progress!
