Well, another one of those DUH! moments for me... ![Icon_crazy Icon_crazy](https://philcoradio.com/phorum/images/smilies/icon_crazy.gif)
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.![Icon_thumbup Icon_thumbup](https://philcoradio.com/phorum/images/smilies/icon_thumbup.gif)
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...
