Yes, I'm comfortable with soldering a new resistor, but the NEC was originally sold with both a NiCd battery pack and a standard Alkaline battery pack. The only difference between the two is the charging resistor and a jumper. I would assume that the power supply would know, based on the type of pack plugged in, how to adjust for this. But I have no evidence of this. I have restored both an original NiCd battery pack and converted a standard pack to be rechargeable. Both show the same behavior. Kurt
