Default reply to Mr. Andrewlebon

Warm regards too Mr. Andrew Lebon.
I appreciate your time and effort for
giving me the schematic of self oscillating
SMPS which is nice and simple although
some of our co-members gave negative comments
about it. I still have to make circuit analysis
myself to know if those problems are true or not.
Anyway here is my email where you can send me the
the details...kiko_antonio71@yahoo.com...Best wishes
to you and Goodluck to our common goal!.Thanks too to all
my co-members who gave response.
