I have a series II interact II bridgeport heidenhain tnc 151a control.
The solenoid valves that control the rpm and brake is gone. A friend of mine told me that the original valve is sort of oddball and hard to get so he put a bank of different 24vdc valves ( not sure of the details) on his. So my question is it hard to find the original valve and if so where is good place to get decent valve sort of cheap? I'm skeptical of ebay for this type of component any suggestions? Right know I have them on a manual valves which is O.k. for now but don't forget to release the brake.
