Project to restore 5720A chassis started

We got the chassis for long-started project of building “DIY”-ish calibrator, using random Fluke boards.

Key component – chassis, has arrived today.

Just few minor dents and scratches, no worries..

Time to reuse my Fluke 5500A front panel parts to merge two pieces into workable front panel.

For binding posts I have an idea how to make it all work..

Film sheet that originally stick between VFD glass and front panel plastic is conductive. It’s some sort of (ITO?) RFI/EMI shield mylar, to reduce radiated crap from high-voltage VFD spitting outside of calibrator.

Put 5700A VFD board in…

Some quick tests with reassembled panel
