I started working on an old Lloyd's 10-band shortwave radio last night. I bought the radio a couple of summers ago for $5 at an estate sale, couldn't pass it up. About a month after I started using it, the tuning needle stopped working.

When it worked, it was great - with a wire spool antenna I was able to pick up Radio Havana very well.

The radio frame is made of leather-wrapped wood, and the back came off with 4 screws. There's a HUGE ferrite AM antenna and a lot of real estate to work with. Once I got everything open, used a bit of white lithium grease from my camera kit to lube the tuning gears.

There's a grain of wheat light bulb illuminating one side of the dial that's burned out, I want to find a replacement before I put it back together. Maybe I could hack in an LED?

While the case is apart, I went over the outside with simple green and the window with glass cleaner. scraped paint residue off of the knobs, and will give the leather a coating of conditioner. It's nice working on something so well made and meant to be repaired.

Last night, I stopped off at Radio Shack; they had a Grundig AM loop antenna for $14.95. It does a great job with my little pocket shortwave unit, which doesn't have an antenna jack. My tabletop SW radio has a mini-jack to plug directly into the antenna, and looking forward to trying it out while direcly connected.

First take a VOM and check that the voltage is for the little light. I would bet its around 12 volts.

I also, find, that LEDS are kinda directional light. So I sand the round tip off the led and sand the sides down to make the light photons spread out more like a filament light.

Also, leds, are low voltage, and you would need a resistor in line with it.

here is a great site that goes into detail on LEDs.

If you knew this already. Sorry for the repeat. http://www.kpsec.freeuk.com/components/led.htm

Also, check if it's AC instead of DC. My rig uses 12VAC for the lamps.

A++ for that. I forgot about that point. Thanks!
