Found an unrecognized black plastic cylinder (1-3/4 inch long X 3/8 inch diameter) labeled “S-10” in my Dad’s miscellaneous electrical ‘junk’ box. Self-tapping screws approx half inch long protrude slightly out each end. Resistance between the screw tips is 11740 ohms, and there is no concentric conductor insulated from the center. Any idea what this might be??S-10 Black Cylinder.JPG

Thanks for your prompt reply Max. Someone with far more knowledge about electronics (than I) wondered about a similar purpose: filtering of paid TV packages by cable providers?? However the absence of a second conductor (as in coaxial cable) would seem to eliminate the filtering option. Truly a curiosity/learning question I will hang onto for future mulling over. P.S. Love your Einstein quote, as I was frequently denigrated by my father for being a "dreamer".

Kind of looks like an old time fix that was used to (supposedly) fix ingition noise in car and CB radios back in the day. You would cut the coil lead and screw the ends into the suppressor and then reconnect the coil lead. This was from back when spark plug wires were still copper not carbon like now.
