se Dyagram ki pati-plasman montre nan Fig. 2. Pran note ke byenke se negatif (tè) plon batri a nan retounen nan tablo a PC, randman-Jack J1 gen yon koneksyon nan tè a kabinè. se koneksyon la tè ant tablo a PC ak kabinè a te fè nan standoffs yo metal oswa bag ke yo te itilize sou mòn tablo a PC nan patiraj la. Èske * PA * standoffs ranplasan plastik oswa bag paske yo pa pral bay yon koneksyon tè ant tablo a PC, kabinè a, ak J1. Si ou deside sèvi ak yon kabinè plastik nan kay anplifikatè a, fè sèten ke se koneksyon tè J1 a retounen nan FOIL la tè kouri otou deyò-kwen nan PC-tablo a.

The parts-placement diagram is shown in Fig. 2. Take note that although the battery’s negative (ground) lead is returned to the PC board, output-jack J1 has a connection to the cabinet ground. The ground connection between the PC board and the cabinet is made through the metal standoffs or spacers that are used to mount the PC board in the enclosure. Do *NOT* substitute plastic standoffs or spacers because they won’t provide a ground connection between the PC board, the cabinet, and J1. If you decide to use a plastic cabinet to house the amplifier, make certain that J1′s ground connection is returned to the ground foil running around the outer-edge of the PC-board.
