Hi. Ireplaced the selenium rect. with a 1n4007 diode and about to replace the 2 section 20uf @ 150vdc cap. I;m using 2 Illinois 22uf@ 500vdc caps . Want to make sure I'm reading schematic correctly..The first cap . Positive side after diode before 1k res. neg side to Blue transformer wire. Cap 2 ,Pos side after 1k resistor which is also ground. neg side tied to cap 1 neg on blue trans wire. the part that confuses me is cap 2 pos to ground. Thanks ...Rob
