Thank you for purchasing White Oak Audio Designs TM-1001 Upgrade Power Supply and Amplifier Board. White Oak Audio Design products are meticulously engineered and tested to ensure a direct drop-in fit for your tuner.
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.
Upgrade board features:
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.
Figure 1 below shows how the original power supply board appears (note I added the small heat sink to my TM-1001 after the first TO-220 transistor at location Q801 in the power supply failed due to excessive heat. It is unlikely that yours will have this heat sink installed).

Figure 2 below shows how your finished project will look (without the optional wiring for the audio output stage).

Assembling the TM-1001 Power Supply board printed
circuit assembly.
Have a printed copy of these instructions with you prior
to performing this assembly procedure.
Skills required:
While assembly of this circuit board is not a difficult procedure, the assembler 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 Power Supply 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 have this assembly performed by a service technician that can perform the Power Supply Board assembly and installation for you.

Assemble from the silkscreen (component) side of the board (the silkscreen side of the board is the side shown in Figure 5). Start assembly with the smallest axial components and progressively add the larger components after completing the smaller components.

Figure 6, Lead Forming Illustration
Installing the TM-1001 Power Supply board printed
circuit assembly into the tuner.
Have a printed copy of these instructions with you prior
to performing this installation procedure.
Skill required:
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 TM-1001 Power Supply 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 Power Supply Board for you.

Step by step installation procedure:
Installing the optional Burr-Brown
amplifier stage wiring to the main tuner board.
1. First step is to locate and remove the 4 electrolytic coupling capacitors from the existing circuit on the tuner main board to ready it for wiring in the new amplifier circuit on the TM-1001 Power Supply and Amplifier Board. These are C316, C317, C320 and C321 and are pictured in Figure 7.
Figure 7, Existing capacitors C316, C317, C320, C321
2. These capacitors can be located just to the rear of the tuning flywheel and to the left of it while looking from the front of the tuner. Figure 8 shows the topside location of these 4 capacitors. The white silkscreen nomenclature will also indicate the accurate location of these 4 components.
Figure 8, Topside location of C316, C317, C320 and C321
3. The locations of these 4 capacitors from the underside of the board vantage are pictured in Figure 9. Carefully unsolder them and use solder-wick or a solder sucker to clear the holes to allow for the next installation steps. Be very careful not to damage the main board while performing this operation.
