Hi Bob, Would it be possible for you to use a relay in between the wiper contact and the trigger tube? Maybe the wiper could drive a relay and you then use the relay contacts to drive the trigger tube, just for testing if that will solve the problem.
The problem with old SRBP PCB's is that contacts that rotate on them leave a track of dirt which will carry leakage currents. Sometimes you can get rid of this by washing them in an ultrasonic cleaner and also by bathing them in isopropyl alcohol, some need mechanical cleaning to remove the conducting track and some are impossible to clean enough which leaves the only option of letting them control a relay that then controls the original circuit. /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
