I did try a 390 ohm resistor, and it made the LED respond *almost* as well as the incandescent. The LED indicator now fades out in one second when I switch the unit from FM Stereo to FM Mono.

However...

I'll have to buy a higher wattage 390 ohm resistor. Calculations show that at 35 mA, the 390 ohm resistor will be dissipating just under 1/2 watt, and the only 390 ohm resistors I have are...1/2 watt units.

So I temporarily soldered an old 430 ohm 1 watt resistor in place (measures 442 ohms), which I will use until my next parts order when I will order some higher wattage 390 ohm resistors.

I think I have that problem solved to my satisfaction. Photos later. I have a 440-T cabinet which I am going to put the 4400 into for the time being until I find another cabinet, and then I will probably put the 440-T in the other thread back into this cabinet since it came out of it to begin with. I had to make a foot for the cabinet, and I have it clamped in place, waiting for the glue to dry.
