What are you using for a power supply now? (Volts & Amps).
How are you measuring frequency?

Jack,

      Car battery.

      I have a UEI DMM with freq/duty/PW capability. The last measurment
I took showed 535hz @ 55%. The circut is built exactly like Bruce B's.
except that I have substituted a .01 uf for the 470 pf cap.

thanx again
