Is their a way to change the range of the speed knob on the Harbinger?
Yes.
;D
Seriously, what are you looking to change? Overall faster? Overall slower? Different taper? You can't expand the range too much (the oscillator has an upper and lower bound), but I can at least tell you how to go about finding the exact maximum range you can get.

Damn that was a quick reply! I am trying to get some slower speeds out of it. I put a second set of caps on a switch for a phase shifting mode.
Actually, if its not too much trouble can you tell me how to get it to sweep faster as well?
Thanks in advance!
Ok, so I read the geofex article "technology of a univibe" and read that the 2 220k resistors limit the slow side and the 2 4.7k resistors limit the fast side. Does anyone know what I can safely change these values to?
