Okay...

Today: Fun (?) with LEDs.

I wanted to convert the dial lamps to LEDs if possible. Trouble was, this receiver does not use fuse lamps. Instead it uses elongated bulbs with a wire protruding from each end.

So, having several green LED fuse lamps on hand, I decided to try to convert them to wire leads.

Using a hot soldering iron, I removed the caps from four LED fuse lamps.

I did not have to solder anything across the two pads on each end, but I decided to do so in order to have each wire centered on each end of the lamps.

Using bits of leftover copper desoldering wick, I soldered bridges across the pads on each end, and then soldered a wire in the middle of each bit of wick.

I bent each wire lead so that there would be a bit of space between each LED lamp and the PC board they were going to be mounted on.

Finally, having already removed the old incandescent lamps, I soldered each reworked LED lamp to the PC board.

They worked like a charm...
