![]() I replaced unnecessary complicated circuit for voltage reference build with IC2 with simple resistor-zener circuit. After that I decided to simplify the schematic even further. I also made changes in the LED drive circuit and a few other minor changes. Consolidated dutchwest federal airtight manual.

Generator klyuchej dlya das xentry.Įxtremal problems on planar point sets Ph.D. Thus total supply voltage for the opamps does not exceed 36V and therefor we may use standard ones. Circuits are calculated to produce 33V positive and 3V negative voltages. First of all I replaced two transistor-zener regulators with LM317L/LM337L. With the original schematic at hand I took the liberty to make a few changes. I found it here: There are scanned pages from the magazine with the original article and eagle files for the project. So, the previous article about lab power supply gathered quite a interest which is not a big surprise considering that there are over 200 pages of discussions in two topics about the schematic in this forum:! I think that the schematic in is not the original one but a modification of an older schematic published in a Czech electronic magazine.
