What do you think about NE5534AN? It's the most similar to MC34071 that I could find in my country! I'm thinking about building new circuit. ;D

One more time, just to check. Is this schematic OK? Do I need some stronger resistors(like in new version)? I have some old 20,000uF 35VDC capacitor, should I test my luck with it or buy 10,000uF 50V? (those are not so cheep is Serbia :-\)

Can you suggest values for those components (main filter capacitors and R14)? Is this mod OK? Do you think it will be good enough for 20V 2A?

I decide to build this project. Only bad thing is, that I saw this topic after buying all parts. After gr8 disappointment, I'll try to build it as good as I can. I draw something between old and new schematic. Please tell me what you think and how can I make it better without changing OPamp. I need about 20V DC output, and around 2,5 Amps for my testings.
