The Lighting Project |
|
|
|
I replaced all 16 bulbs in the light board. After assembly I was disappointed in the lack-luster appearance of the display. The yellow cast of the incondecent lamps left a lot to be desired. So I converted the whole setup to color coded LED |

I started by pulling all the bulbs and sockets. The output 1 and 2 lamps on the right are driven by 12VDC, through the 120 ohm resistors on the board. The powersupply already has a 12v DC output for this. Converting this was a simple task of upping the resistor values to cut the voltage to 3.5v. The rest of the lamps took a little more effort. Below I have started the upgrades to the board. |

Completed board below, looks much cleaner without all that hardware... |

My miniature power supply....
The bulbs are 6v AC. The power supply supplies an 8VAC feed to these lights (which compenates for the resistance votage drop accross the lamps). I built a small half-wave rectified power supply and mounted it just behind the light board. It is spliced into the 8VAC feed (brown wire) with a ground (black) for the smoothing capacitor. It productes a smooth 3.5VDC output. I then added a couple of jumbers on the light board so the current flow was not serial accoss a along srting of LEDs. Works very well, and dresses up the display to look waaaaayyy cool... |

Cool green, blue, and white for the output indicators...
Green (tuner, Aux, Phone 1 & 2, Source, Mode, Pre-Amp), Blue (Tape Mon A & B, Stereo, Mono, Reverse, R & L), White (Output 1& 2) |
