Alton: Here is a direct dial to eastern voltage research from Dan  
McCauley's current business card. Hope this helps. 1-856-599-8375.
 
Good luck,

Hi
I am building a microbrute drsstc by  eastern voltage research and 
i am have problems
and need some help. I  finish it yesterday and was trying to fire it off 
and got nothing so  by
the book i reverse the polarity through the current transformer that  
didn't work.
All the voltages are right check them 3 times the LED's  light up, the 
over current led come
on when I ramp the PW control up. I  took the board out check all solder 
joints and check
ever IC twice to  make sure it was right. I tested ever diode and they 
were good, ever  cap.
was check twice, I ever check the controller and wave from twice, i  even 
compare the wave form
to another controller i have. I even ohm the  primary and secondary out 
they were good.
Unless the IGBT are open i  don't know what else it could be. Also no 
blown fuses neither.
I am not  the best at this but i did have a radio/TV repair shot for 27 
years so  this isn't new
to me. I can send detail pictures if someone can compare to  there's. I 
will thank anyone
for the  help
thanks
