Here's the one I designed for my ASM-1.  I've never seen another
saw-tri design that puts the transistor in a feedback loop like this,
but that's not to say it hasn't been done before.

The opamps I used are TL082s.  I'm using the same NTE JFET in the VCO
as you so the glitch filter should work as designed, but you can tweak
it if necessary.
