PCB Assembly 1. Bend resistor leads 90° as shown for insertion into PCB. This Should be done one type at a time to avoid mixing up the values and placing a resistor in the wrong place by accident. These parts are non directional but must be installed in the correct location. - Page 4 6. Install and Solder LED1 and SW1 to the board, both parts are directional and should be installed as shown below. 7. Install and solder Con1 - Con4, as well as Pot1. Some pins on Pot1 are close together, take care not to bridge any of these pins together when soldering.
- Page 5 9. Install and Solder C1, C2, C4 and C5 (these are directional and must be installed as shown below). Again all of these parts are the same height and if the opposite side of the board is temporarily supported soldering will be easy. 10.
- Page 6 14. Test fit the board on top of the spacers, with the board fully supported by the spacers only there should be nothing touching the aluminum panel, fix/trim/resolder as required. 15. Place the lock washers and nuts on the screws protruding through the board. Do not over tighten! This will compress the 1/8”...
- Page 7 17. Flip the amp right side up and loosely install the top panel using the four remaining 4-40 x ¼” screws, do not tighten. 18. Install the back panel using two of the M8 screws, do not tighten. 19. Assemble the four amplifier feet as shown below, do not tighten! The square nut must be free to slide into the t-slot on the bottom of the amplifier.
- Page 8 20. Slide two feet into each slot on the bottom of the amplifier, the screws can be tightened slightly but the feet should still move within the slot. 21. Install the front panel using the remaining two M8 screws. Tightening these screws should slightly recess the screw head into the pockets in the front panel as shown below.
- Page 9 23. Move the feet to the desired locations, I suggest the front feet should rest flush up against the back of the front panel, and the back feet should sit on or just inside the back panel as shown above and below. After the screws are tightened peal off the rubber feet from the backing and install them into the recess in each foot.
