looking for a psu schematic with plans for laser printing a pcb

[p.larner]

has anyone plans for a psu with a layout for laser printing onto a pcb toner transfer method?,i have an old millitary psu with a blown up control board,it has lots of taps from 3v to 43v,its about 7 inches square i want to buld a 0-60v 0-30a unit if poss with cc+ cv.

You don't need artwork specific to toner transfer etching, although a long and time honored PCB making method is to use photocopies of the PCB artwork in magazine articles (you might actually want to look through magazine archive sites, eg https://www.worldradiohistory.com/index.htm It's a shame old Elektor issues have become hard to find). These days, mirror imaging , capturing, scaling, cleaning up etc. are simple tasks.

found this but the 723 is good for 37v max does the zenner going thru the 100k resistor to pin 10 on the 723 lower the input to a safe voltage for the 723?,may need to zoom in as its a screen shot ok,cheers.

use 723 in floating mode .... you could design higher voltages output
