Hello, I like your web site. I'm interrested about 0-30 VDC STABILIZED POWER SUPPLY WITH CURRENT CONTROL 0.002-3 A and have couple of questions. Is it possible to increase output current to 5 Amps ? (adding 2N3055 and changinging some component values) Can I built 2 similary power supply and use it in serial mode 0-60 V or in parallel mode to get more current 0-10 Amps or use it like dual power supply +/- 30 V ? Thank you Tomislav, Croatia ???
