I had the Mutron II back in the 80s and it was noisy and broke fairly quickly. If you were going for the Biphase sound/effect many modern pedals could achieve the same effect more cleanly, quieter, and with more flexibility in sound shaping. I have to get on my H90 soapbox and state you could easily get the same effect out of the Eventide with the ability to put the phasers in series or parallel. You could also try different phaser types like an MXR 90 or Small Stone. If you bought the Mutron you are paying collector's pricing, typically $500–$800 for an out-of-warranty pedal that has seen decades of use. Important to note you would need the Eventide H90 to achieve this, the Eventide H9 will only do one effect at a time.
With some fuzz or distortion yes you would get the jet whooshing sound with the phase set just right. However I think that would be easier to achieve with a single phase or flange.
