Yeah, you said it. I've also got a QX-949, but luckily no vintage refrigerators.
As much as the over-built, last-a-lifetime quality is a big component of owning of these old appliances, I can imagine how that fades when it's an object that weighs 800 pounds instead of 80.
I'll have to decide whether to fix those, and whether to use appropriate[1] LEDs or find some correct incandescent bulbs, or just leave the lights dead, before it gets sold.
Thoughts?
(I'm strongly in favor of low-color-temperature white LEDs. They should live ~forever if not pushed hard, and they should look the ~same as the tungsten bulbs did in 1970-whatever. But low-CCT LEDs are tricky to find, and they're often designed with light dispersion characteristics that don't match those of an old-school light bulb.)
The lights are generally not reliable on the 949 - particularly the radar display on the front-left (vumeter per channel, basically), so that’s also worth a service, if you can.
After that it’s the caps, as you probably know. The thing is with the quad ones, there’s literally two of everything in there.
Best of luck with restoring and selling it.
