HP ET0004 Variable AC Power supply
« on: September 09, 2022, 09:35:59 pm »
Does anyone have a manual for this vintage variac? It looks similar to a 431b power meter case style with the knob mounted on the top case. So around 1970s vintage. However I cannot locate in in the hparchive catalogs. Thank you.

The ET model number prefix indicates that it is an HP internal production test gear item. You will be very lucky if you ever find any published information on it.
