Brand new upgrade blank PCB to replace the original TM-1001 Power Supply board with an dramatically improved power circuit.
This classified is just for the bare board.
Do you own a Realistic TM-1001 AM-FM Tuner? It is a great tuner but the original power supply is holding back the true performance and reliability achievable on this remarkable, low cost tuner. Here is your opportunity to replace the original board with a reliable, high performance replacement.
Other parts must be obtained by the purchaser from Mouser Electronics to complete this upgrade. The cost of these parts is less than $13 from Mouser, not including shipping. Detailed photographs, assembly, parts list and installation instructions are located at this link in this ad.
The assembled and installed upgrade Power Supply Board will convert your TM-1001 tuner power system to a quieter but more robust and reliable power supply than the original one supplied in your tuner. Power supply board failure is quite a common cause for failure in the TM-1001 tuner.
This upgrade board features:
* Low noise rectification circuits utilizing high speed, high performance, and low noise Schottky barrier rectifiers replacing the original standard recovery silicon rectifiers. Schottky barrier rectifiers do not have the reverse recovery current noise effects of the original rectifiers used in the TM-1001.
* The original Auto-Magic circuitry that the TM-1001 made famous with upgrades to its function with higher quality components than the original.
* Improved AC line power factor due to soft rectification circuitry.
* Significant increases in the input and output capacitance on the positive and negative voltage rails.
* Symmetrical plus and minus 13V precision linear regulators to replace the original zener based voltage regulators. These regulators employ short circuit current protection as well as thermal protection and shutdown in the event of downstream circuit malfunction.
* Heat sink provision for both the positive and negative voltage regulators. Mechanical tie down provisioning for the large power regulators adds to the reliability of the power supply.
* Quality, precision, low noise, 1% tolerance, 50 ppm metal film resistors used throughout to replace the original 5% carbon resistors.
* A high quality, double sided, FR4 epoxy printed circuit board with white epoxy silkscreen on component side to replace the single sided phenolic PCB used in the original TM-1001 assembly.
* Clear, concise schematic and assembly drawing for the upgrade Power Supply assembly
* Direct drop-in mounting and wire for wire numbering match with the original PCB.
* (Optional) A high performance, low distortion, Burr-Brown or Analog Devices audio grade amplifier stage to replace and enhance the final audio output of your tuner. The amplifier scratch pad area allows you to tweak the audio performance of the TM-1001 to suit your preferences.
* (Optional) High quality silver mica and polyester capacitors used in sensitive audio path circuits.
In addition to longer life, the overall power consumption will be reduced as well as heat generated inside the enclosure. Your tuner will have a Power Supply that will substantially extend its useful life.
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 screws 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 PS 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 PS Board assembly and installation for you.
