Beomaster 1900 (Type 2903): New Program Function Lamps

With the replacement LEDs on the Bass, Treble and Balance indicators working out so well I decided to change the seven program function indicators to LEDs as well. They will just be a single LED component with a 1KΩ current limiting resistor.

I did one to test how the LED compares to the original incandescent lamp. The first lamp in the program selection group is the far left lamp - Phono.






















Looking at the original lamp illumination on the Tape selection I have this























The new LED Phono lamp looks like this























That looks good to me so on with the other six lamps. As with all of our replacement components these LED plus resistor assemblies are drop in replacement for the original lamps. If someone wants to return to incandescent lamps in the future they can easily do that. However, these LED components look the same and run cooler.












Now to put everything back together and see how the Beomaster looks and works.
































Very nice. Now let's look at it a little closer in.





















I think this Beomaster 1900 project is very close to a wrap. Just another few days of testing are needed.
