Anyone have manual/schematic for Power Designs 2020?
« on: October 10, 2014, 04:51:19 am »
Does anyone have a manual/schematic for the Power Designs 2020 Precision Power supply? I have the manual for the 2020B, but this unit is labeled 2020, not 2020B.

Thanks, but I already PMed robrenz before I posted this thread. As it turns out, he does not have a manual or schematic for the 2020, only the 2020B. The 2020B appears to be significantly different (it evens appears to have an IC). Just looking at the components in this thing it looks a lot like the 2005 as robrenz mentions in that post, but ther are differences and the components are spread out over 3 circuit boards versus the single board of the 2005. I was hoping to get the manual as this one apoears to be in need of repair.
