Well, another one of those DUH! moments for me...
After some experimentation with the receiver tonight, I noticed that I had forgotten to add a 300 ohm resistor in parallel with the green LED replacement of PL5.
So, after adding a 300 ohm resistor across PL5, I tried it out without jumping a resistor across R715. When Auto Magic was turned off, PL5 dimmed slightly and PL6 (the white LED) did not light at all.
Then I jumped a 1000 ohm resistor across R715.
The circuit now works as it should. The white lamp comes on and the green lamp goes out when I turn Auto Magic off.
I'm going to replace R715 with the 1000 ohm resistor and call it fixed.
Thanks again for the assist, Mondial.
I'm waiting for some lamps to replace the dial pointer lamps, then I can button this one up and call it finished, I think...
