Do the people who write these articles ever bother to see what they look like when they get published?

I mean, COME ON, EE Times!  WAKE UP!  This is such a joke.

A tuned filter?

My first thought would be a tuned LC filter, resonant around 120 Hz. That would have avoided the noise problem and been far more reliable, and a whole lot cheaper.

When I was designing test equipment for factory floor operation we almost always put a Sola Brabd constant voltage transformer ahead of the controls and instrumantation power input. It was always cheaper than even one service call to fix a machine, and it gave us a reputaion for producing very reliable testing machines. The noise on the waveform on the scope traces looks a bit like it comes froman inverter drive circuit for a medium horsepower motor.

that is the funny thing about so many stories involving solving a problem. Someone always comes along with a single sentence that would have probably saved you hours... a long time after the fact.

It's not so easy to create a monster :)

Though the schematics are difficult to read I can identify some R's on the primary side. Thus an adequate C should have done the trick.

Wouldn't a simple RC filter have cleaned up the 60 Hz to get a stable clock?
