[sdiy] ASM VCO tips wanted.....

Hello all, I have my ASM here, and one of the oscillators wont oscillate.  I've gone over the thing numerous times and have replaced the 3140, 311, and the FET (its now a 2n3819 this should be OK right?)
here's the schemo:

(thanks Gene Stopp!!)

anyway, all the panel controls and jacks check out OK, and all the resistors and caps are the exact same as the other osc (which works)  The voltages at the chips are all OK, and the trimpots are okay too.  
The SAW out isnt stuck at +v, but instead I noticed that the voltage at SAW out slowly decreases, and the rate of decrease increases when I reduce the value of the cap on the FET.. : ) follow that?  heheh
so it basically acts like a very low freq osc.  the panel controls have no impact on this rate either... 

so, if anyone has any ideas about this I'd be greatly appreciative!!  I'd like to get it fully operational and now that Ive spent many hours mulling over the circuit, i'm officially on a mission!!!!!!!!!!!!!!!!!!!

thanks all,
see ya at AHNE!!!!!
