Steve,
I had exactly this same problem, MKH 20 into 702. And yes it was the
left channel too! I swapped over the mics, and then got intermittent
fizz in right channel, so I then knew it was the mic. Mic was
repaired under warranty, they did not say exactly what they had done
other than 'repair fault'.
