10 Transistor T6 16. Mounting the transistor T6 on the heat sink: Apply a drop of heat conductive compound in the heat sink hole (fig. 4.0). Fig. 4

11  Insert the transistor (BC547) in the hole (Fig. 5.0). Pay attention to the position of the transistor (fig 6.0)!  Carefully

12 Power transistors  Apply a drop of heat conductive compound on the heat sink (see fig 8.0.)  Mount the isolation mica onto the heat sink, check

13  Solder the connections of the power transistors with the pin headers, see fig. 10. Fig. 10 Power transistors

14  Use a 2 x 25 to 30Vac / 100 - 120VA transformer.  Connect the transformer to the AC power connections of the PCB.  The Velleman transformer

15 Test & adjustments

16 Test & adjustments  Turn the RV1 bias adjust trimmer fully counter clockwise (turn left) before applying power for the first time. ADVICE:

17 Final connection:  The input (GND and in) can be connected directly to an audio source (pre-amp or mixing panel) or a vol-ume control (potentiom
