Ken's comments above are exactly spot on. I think you might have some success retrofitting an LED for the job- that way you can set the current (by bypassing the LED with a resistor) such that the unit will work without your finger on the sensor.
Electrical issues with Philips GA 212 Electronic
Hello all -
trying to get an old 212 to function. Replaced all the light bulbs, main switch is sound. TT starts as normal with the use of the touch panel, but stops as soon as the finger leaves the panels (33 or 45). The photo cell looks normal. I've tried to shortcut the photo cell circuit to see if the problem originates here, but with no luck. Any ideas what's causing the TT's unwillingness to work?
