Folks!

You dont need any super specialized clipping things,
nor any 4000gates for supersharp edges (even if its nice to have,
well if you want absolute precision it can be neat to have , 
but the rounding of the saw wave, and retrace time at high
frequencies will "showel bang" it up anyway) no specialized
CV inputs for phase! (who asked for that?) ugh, and ugh again!!

You need:
1: a saw wave, 0 to +5v or 10V in peak unipolar or bipolar.
2: a PW wave ,0 to +5v or 10V in peak unipolar or bipolar.
3. add them with 100PW/50saw blend in amplitude and you get saw phase shifting.
4: add them 100saw/100PW and you get phase shifting saw wave, 0-180 degrees.
5: The sawphase wizzard has spoken,thank you very much! :-)

After words:
In any additive wave thing in wich phased saw waves actuaclly are
wave amplitude are the crucical inferno. So dont base your phase
waves on the asumption of stable power supplies! ugh!.
Its very simmliare to the basic saw to triangle converters!

Right, ages and ages ago! Ooh, now im starting to feel very old and crippled!
