Power Amplifier - Special Instructions
Caution:
As the location of certain components in the PA is critical to performance,
it is important that any components removed or disturbed are refitted in
exactly the same location.
3.3.1
To Replace PA Transistors
Desolder the tabs by heating them with a soldering iron, then lifting them up
towards the transistor with a thin stainless steel spike or screwdriver.
Unscrew the transistor mounting stud nut or screws and remove the transistor.
Trim the tabs of the replacement to make them similar to the faulty item, then
lightly tin the underside of the tabs.
Apply a thin layer of heatsink compound to the underside of the transistor.
Screw the transistor tightly to the heatsink then solder the tabs.
Do not solder the tabs before tightening the screws or nut, as this will fracture
the device.
3.3.2
To Remove Case Mica Capacitors
Apply a heavy duty soldering iron to the top of the capacitor case.
When the solder is molten, ease the capacitor away from the PCB with a thin
stainless steel spike or screwdriver.
