tandberg: TP41; Portable

The Tandberg TP41 contains a voltage stabilizer called a stabistor which is very unreliable and almost always fails after a few years. On examining the PCB, a green powder can often be seen leaking from the component. The symptoms are instability and squealing on the sound. An easy replacement is to use a red light emitting diode, giving a voltage drop of around 1.5v to replace this. I have carried out this modification on my own model to great success.
