3 assembly hints 1. Assembly (skipping this can lead to troubles ! ) ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 make sure you have the right tools: • a good quality soldering iron (25-40w) with a small tip. • wipe it often on a ...
4 1.3 soldering hints : 1- mount the component against the pcb surface and carefully solder the leads 2- make sure the solder joints are cone-shaped and shiny 3- trim excess leads as close as possible to the solder joint remove them from the tape one at a time ! Assembly hints do not blindly follow ...

8 slide the pcb in the largest slot of the heat sink. (see fig. 1.0) note : if the optional thermal protection is used, a hexagonal bolt should be slit into the mounting slot, and into the hole in the p.C.B. Then the thermic may be mounted on the heat sink and its terminals may be connected to the p...
9 two transistors are mounted at both ends of the heat sink (for their positions refer to fig. 3.0). T1 & t2 : tip142 of motorola! T3 & t4 : tip147 of motorola! Fig. 3.0 bend the connections of each transistor as in fig. 4.0. Put them in the correct position on the heat sink and against the p.C.B., ...
10 apply a drop of paste on each transistor and put them in the correct position on the heat sink and against the p.C.B. Make sure the correct type of transistor is placed in the correct position (t1...T4). Fix the transistors well in place by means of the supplied plate and a hexagonal bolt, which ...
11 connect a symetrical power supply unit (possibly the aps200, sps200 or k3508 module) of + and - 30 tot 45vdc to the positions gnd (0v), -v and +v. See fig. 7.0. Important: do not switch on the supply voltage before the connections to the amplifier are made! Switch on the supply voltage. Normally ...
12 fig. 9.0 2. As a mono-bridged amplifier: • see fig. 9.0 for the connection of the power supply and the speaker. • make sure that the impedance of the connected speaker is not less than 8 ohms. Important: always connect the outputs first, before the power supply is switched on. If the amplifier is...
