How can corrosion on the 41C contacts be repaired?


Do they sell new contacts and how much do they cost? Also where do they sell them?


See "repairs & batteries" on this site and go to 41CX repair page ( for one possibility. Replacement contacts are not available, although you may be able to find a parts calculator that has good terminals. Corroded terminals and cracked screw posts seem like the two biggest reasons for 41s to die.




They would have come in handy for me a several times. I don't know how often I would buy them, but for the HP-41 series I would buy two sets today for $20.00 each.
