MOTM

Howdy,

I assembled my 320 and it's not working according the specs.
With speed knob on 10 i have a frequency of 85Hz, with the same knob all 
the way down, nothing is happening at all.
Actually nothing is happening when moving the speed knob from 0 to 4. 
well, the voltage changes, but that's it. Speed knob at 4.5 it suddenly 
starts oscillating at 4.1Hz.  I've looked at the output for quite some 
time now, and I'm very sure I see nothing happening with the speed knob 
below 4.
I checked resistors and all other components, looks good to me.
Also, the trouble shooting section speaks of some pins of U3&U4 to check 
for some waves, they are there all right. I don't know what the 
frequencies should be at those points though.

Any suggestions?

Enjoy the holidays!

Cheers,
