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 the position of the hole.

Apply a drop of heat conductive compound on the mica.

 Carefully bend the leads, see fig. 9.0

 Mount the transistor on the heat sink, using a bolt, washer, lock washer

and nut.

IMPORTANT: If metal body transistors are used, a plastic

isolation washer must be applied (see 9.0.)
