And burning it was. Rob now had the highest potline voltage seen on the
line in recent years, and there apparently wasn’t a single thing anyone could
do about it. For ve days, the team had been working on what was causing

Steve Harris was hunched over the computer console, looking at the
voltage numbers pot by pot, and looking much older than he did six months
ago when he had started.
Nominal voltages hadn’t changed, but the actuals had, and the driver was
the noise voltage. That muc ...
