John,

3579.545 kHz color burst crystal
You are right! Thanks for the tip.

I don't know if it is "easily pullable" though... I remember trying a "32 pF
parallel 3579 rock" in series resonant mode but I did not get lower than
about 3579.3 kHz. The oscillator was a two transistor thing with the xtal
connected between the emitters (xtal sees low Z = preserve the Q).

Perhaps it will work with some additional inductance in series with the
xtal but the Q will suffer I guess...

Maybe a *very* low quality xtal will do the trick (lower equivalent L/C = lower 
Q)?

Do you have any circuit suggestion for a suitable "rock bender"?
