Philips PCS150 Enlarger (02)
Philips Medium Format Enlarger PCS 150.
So, during the first test of this enlarger one of the color heads lightsources (a halogen bulb) quit working. 2 minutes later a second went dark, grrrr... :-(
After some measurements i discovered that this color head has a weak spot. The leads from the bulbs were oxydised (see green arrow) and when the bulb became hot the electric contact inside the plug got lost.
I cleaned the leads with a piece of fine sanding paper and a dose of contact cleaner.
