[sdiy] MiniMoog envelope output level

Hi guys,

Quick question: what's the maximum level a MiniMoog (model D, original issue) envelope generator can put out (into the VCF, with contour knob fully open)? I'm thinking about  adding an invert switch to this circuit with an opamp fed from +10V/-10V as available on the cutoff pot, however, I'm wondering if a TL072 has sufficient headroom. 



ps. I know, I could measure, but I'm lazy, and this Mini (a rack-mounted SE unit with original Mini VCF) is not fully running yet.
