I'm replacing the lamps with LEDs on my KR-6400. My tuner needle lamp works, but I figured I'd try to replace it while I'm in there. And I'm not really sure I can. It looks like it's one sealed contained unit. I got this small LED in my lamp kit which I assume is for this. Should I even bother? If this ever did go out what would my option be?

Did they have another for the Stereo light? If not more likely stereo light. Left the one in my KR-7400 alone it worked. Have done the pointer bulbs a number of other vintage receivers
Bulb should be held in place by some kind of adhesive at the end of the black and white wires. You probably have to take something to chip it off/out to free up the bulb. Tip of Xacto knife blade, small flat blade screwdriver with tip around the size of tightening eyeglass frame screws might be even better. Should be a tiny bulb maybe 3 mm in diameter is typical in pointers.
Looking at your third picture I think I can make out part of the bulb inside the upper part of the pointer.

Yeh came with another for the stereo lamp. I got everything replaced except this dial pointer lamp... which I dont know if I want to do now. "If it aint broke..." These receivers are kind of a pita to do a bulb replacement!

JF, can you mention where you purchased your bulbs? Thanks in advanced.

I think I'm going to add a thin acrylic diffuser. I'm getting hot spots. It's not very apparent in this photo but very apparent in real life.

I gave it one more go and I think I solved the hot spotting. I truly tried a dozen different things until I stumbled on this. I ordered this sheet of photoshoot gel diffuser.
I folded it so it would be 4 layers thick, and then folded that in half to create a "V". I cut that into pieces just wider than the LED bulb. I took those pieces and put them directly in front of the bulb and held them in place with a dab of hot glue. Hot spots GONE. I put them on the tuning meter lights to to equalize the lights. This really mellows out the LEDs.
