Thanks. I've had a look at the EML200 master osc, but I'm fairly
certain it's not the same as the osc had the schematic for. The one I've
seen had a ten way range switch (and not in decades), and it had sync
and a CV input with reversible attenuator like most of the early Serge
modules. Maybe it was inspired by the EML?
