While waiting for a suitable tube for my HGM-20, I recently acquired a Omnichrome 543-300A-NORN laser head (yes, this is an addiction).
Applying an Oudin coil, the tube clearly ionizes and is vacuum intact.
Base on documents I found searching the web, it appears this head uses a Model 170B or 176B power supply. I have neither one of these, however, I do have a model 171 power supply.
Apparently, the 171 PS is for the Omni-643 head. What is the different between the 171 and 170B power supplies?
Does anyone know if a model 171 power supply will work with the Omnichrome 543 laser head?
Thank you,
Willie
