acca i have about 15 bu508 transistors...
can i use two pairs in parallel for each smps?
If change value of R3 more higher will make frequency up or down @Acca?
Here's waveforms in BJT schematic,and first picture is H bridge FET version.This is pctures from my friend.He winded 8turns on BDT primary instead of 4,because,as he say,it work better
His BDT now have 8t and 2x4t for bases.

Your Schematic work perfect.. I set output +/-15V with 2x5 Turn. But i don't get 20V..
