Hi Al,
I think I have a box of variable capacitors in my shed, I'll check tomorrow (Wednesday).

    Gang,
    
    The Museum crew has become involved in the IEEE Engineering    Mini-Academy program, an undertaking to inspire high-school students    to a careers in engineering.  We'll be participating in February.     One of our exercises is the assembly of a simple FM transmitter    using one transistor, emphasizing the concept of "breadboarding.".
    
    
    
    After assembly the kids get to attach their mobile device, and see    how far away they can hear their favorite music.  We did a test run    of this last evening, victimizing some 11th graders.  It was a    notable success.
    
    Now we need to gear up to produce about 10 kits.  Most of the parts    are easily available on Ebay, directly out of China for almost no    money, but we need some variable capacitors.  Something in the    neighborhood of 50-75 pF that's easily panel mounted, and has a 1/4"    shaft.  Like these:
    
    
    
    What's out there?
