Thanks Maus45 and Crius, I found some on line with that P/N....should be here soon!!
I also found a solenoid, after using 'electro magnet' instead of solenoid in the search engine. Amazon apparently has many listed (who knew?). BTW, the one 35rc.com uses is a 20x11x12mm sized one with a 12 ohm resistance coil. If anyone is interested....
