Q1 and Q2 are MPSA18's and I socketed Q3 as I dont have the 2n2907A that it calls for. no matter what I've tried subbing in (BC179, 2N4125, 2N5401 only because they're on hand) I can get it to sound ok, but only with the oscillation all the way down. If i move it pretty much at all - squeal city.
Are there certain values for the MPSA18's that i should have looked for? is it possible that my hfe on Q1 and Q2 are too high?
Thanks
