Brand new, upgrade blank PCB to replace the original incandescent light bulb board with a long life, low power, LED based board assembly. This classified is just for the bare board and the link to the assembly instructions.
Do you own a Realistic TM-1001 AM-FM Tuner? It is a great tuner but maintaining the original incandescent meter light bulbs can be a nuisance, Here is your opportunity to replace the original light board with a long life LED powered replacement.
Other parts must be obtained by the purchaser from Mouser Electronics to complete this upgrade. The cost of these parts is less than $14 from Mouser, not including shipping. Detailed photographs, assembly, parts list and installation instructions are located at this link at the end of this listing.
There are 3 ultra-bright Blue LEDs for each meter providing a consistent wash of light for meter illumination. You can choose either white or blue LEDs for your application depending on which LEDs you populate (blue LED part numbers are specified in the parts list).
The LEDs are powered with a forward current of 13mA to provide bright, pleasing illumination while reducing the power requirements by over 80% from the original board. A current control resistor is provided for each LED allowing you to tweak with the illumination level if desired.
A rectifier bridge is located in the center of the board surrounded on the left and right with 2 filter capacitors. This combination provides a smooth DC source for the LEDs. The cool running LEDs eliminate the heat associated with the original equipment incandescent bulbs and last indefinitely. No more replacing those hard to find bulbs!
The printed circuit board is a high quality FR-4 based epoxy glass PCB with immersion silver plating on the solder pad areas replacing the cheap original single sided phenolic based PCB. The replacement PCB is 0.062 inch thick double sided circuit board with plated through holes and white epoxy silkscreen legending. It is a direct drop in for the original board size, using the original plastic rivets to secure it in the tuner.
This upgrade kit is for skilled technicians. While installation is not a difficult procedure, the installer should be familiar and comfortable with working on electronic equipment and using a soldering station and associated tools. Ensure good control of soldering iron temperature, not exceeding 600 degrees F, so the LED Light Board is not ruined by excessive heat. If you are not familiar with working on electronic equipment or do not possess the proper equipment, it is recommended that you take your tuner to a service technician that can perform the LED Light Board for you.
