Hi guys,
I found a dead Keithley 2001 in the dumpster two years ago and tried to revive it. After replacing all leaking caps and broken diodes, the high current resistor, and a destroyed trace, there is one (obviously) dead part left, which I could not yet replace. The VFD inverter ERG E705-E905VF also contained an exploded cap and other burned/etched components. Unfortunately I destroyed the transformer, when I dug out the components from the epoxy. Tektronix would only sell me a whole new digital board, and erg power does not have any spare parts left. I already tried to reverse engineer the part and rewind a transformer on a new core but unfortunately I did not get it to work. I'm a chemist and electronics is just one of my hobbies, so maybe I got something wrong, like the magnetic specifications of the core material, the winding or details in the connections.
Does someone here have a surplus inverter brick which I could buy?
Thank you to all for the priceless info you put on this forum
