Barbouri's Electronics Projects
Restoring vintage electronics along with designing and building new circuits. One eye looking into the past, the other looking into the future.
Checking out a HP 3551A sold as “For parts or not working, will not power on”, that I actually purchased for parts.
My original intent on purchasing this unit was to salvage the knobs and connectors for repairing some of my other HP gear. I did manage to swap out four of the knobs before my curiosity got the better of me.
Cleanup and repair of a Hewlett Packard (HP) 8012B pulse generator purchased on Ebay as “Untested does not power on, sold as is”.
The 8012B was originally produced by the HP Gmbh Boeblingen Divison, Germany, but this later model was made in USA. It provides variable transition times down to 5 ns and the repetition rate can be adjusted from 1 Hz to 50 MHz.
