Preparation for Checkout

 In this step you will connect the transformers up to the board temporarily in order to power up the board. This is done because the transformers will probably need to be disconnected from the board for final mounting. If the final mounting position allows full access to the board it may be possible to mount the board before proceeding to the checkout page.

  You need a clean work surface with enough space for the board, the 3 transformers, 3 multimeters, a power strip and all of the associated wiring. If you want to perform a complete listening test, you will need speakers and a CD player or other source. These should be located out of the way with the wires and interconnects leading into the working area. There must be access to the CD player in such a way that you can't touch the CD player and the board at the same time. This is an unsafe situation. You should never use your good speakers to power up a new amplifier. If there is a problem the speakers could be damaged.
