1/2 volt saw from the core, I don't need a gain of 6. Also, as I'm
seeing the positive rail at the output of an inverting amp, that must
mean the offset resistor is too low. Perhaps these two resistors
were to be the other way around!
By the way, Ken, I've been playing with the core of this VCO. When I
get this sorted out, these VCO's will see some heavy usage! A very
nice design, in my opinion. Easy to set up, lot's of modulation
possibilities, the sub oscillator and the VC saw/sine shaper which is
really the icing on the cake.
To everyone on the list- this is really MY error, not the pcb or the
design. And it may seem like I've been working on this for a long
time, but that's because I don't really get enough time to work on
it - a few minutes here and there. Thanks for your suggestions and
ideas! Buy lots of Ken's VCO's, too.
