My Palstar tuner had a broken lightbulb for quite a while. I was a little irritated that it wouldn't turn on so I decided to change the original light for a green LED I had in my junkbox. Since I had to open the tuner also cleaned the interior and the coil/coil wheel/wheel shaft. All parts were certainly very dirty and I had to clean everything multiple times.

The wheel that makes contact with the coil was almost black inside. Don\t know what causes this?

At first the LED was too bright. I was glad I installed a VR to dim the light.

Does anyone have a good idea to refurbish to lettering around the antennaswitch? It comes off unfortunately. It already did after a year or so. If I knew this would happen I had certainly made precautions and would protect it.

Hoi Bas
Kan het zwart wordende wieltje niet zilver oxidatie zijn?

Hallo Martin, dat zal het waarschijnlijk zijn. Ik merkte het ook al tijdens het tunen op RX. Vooral op de stukken waar ik vaak zend. Heb het gereinigd met contact reiniger, dat ging goed. Na verloop van tijd zal het wel weer gaan oxideren. 73, Bas
