170V is far below the ozone risk, only in case of arcing it could be possible. Could it be some traces are too close together and be a possible source of arcing? Many people in this modern semiconductor time aren't aware of the minimal safe distance between traces. Also nobody cares the voltage limits of a resistors. Not a point with a voltage of 170 volts, but working with CRT's and high speed dekatrons it may be quite an issue. eric

Did you see any telltale residue with a greenish tint ? Was the damage confined to areas around electrolytic caps ? They do contain corrosive electrolyte and can fail over time. The only other thing I can think of, and this is a long-shot, is ozone. If the case is tightly sealed it's possible the HV areas have a high enough field strength to some ozone. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
